In this article we present a survey of transport protocols for Wireless Sensor Networks (WSNs). We first highlight several unique aspects of WSNs, and describe the basic design criteria and challenges of transport protocols, including energy-efficiency, quality of service, reliability, and congestion control. We then provide a summary and comparison of existing transport protocols for WSNs. Finally, we discuss several open research problems. W ireless sensor networks (WSNs) generally consist of one or more sinks (or base stations) and perhaps tens or thousands of sensor nodes scattered in a physical space. With integration of information sensing, computation, and wireless communication, the sensor nodes can sense physical information, process crude information, and report

Abstract—A wireless sensor network with multimedia capa-bilities typically consists of data sensor nodes, which sense, for instance, sound or motion, and video sensor nodes, which capture video of events of interest. In this survey, we focus on the video encoding at the video sensors and the real-time transport of the encoded video to a base station. Real-time video streams have stringent requirements for end-to-end delay and loss during network transport. In this survey, we categorize the requirements of multimedia traffic at each layer of the network protocol stack and further classify the mechanisms that have been proposed for multimedia streaming in wireless sensor networks at each layer of the stack. Specifically, we consider the mechanisms operating at the application, transport, network, and MAC layers. We also review existing cross-layer approaches and propose a few possible cross-layer solutions to optimize the performance of a given wireless sensor network for multimedia streaming applications. Index Terms—Cross-layer mechanisms, medium access con-trol, multimedia, video streaming, wireless sensor networks. I.

Reliable dissemination of bulk data is one of the important problems in sensor net-works. For example, programming or upgrading the software in sensors at run-time requires reliable dissemination of a new program across the network. In this paper, we present Infuse, a time division multiple access (TDMA) based reliable data dis-semination protocol. Infuse takes two input parameters: (i) the choice of the recovery algorithm (from one of two presented in this paper) to deal with unexpected channel errors (e.g., message corruption, varying signal strength), and (ii) whether a sensor should listen only to a subset of its neighbors to reduce the amount of active radio time. Based on these parameters, we obtain four possible versions of Infuse. We com-pare the performance of these versions to assist a designer in selecting the appropriate version based on the network characteristics. Furthermore, we demonstrate Infuse in the context of network programming.

We propose an In-Network Data-Centric Storage (INDCS) scheme for answering ad-hoc queries in sensor networks. Previously proposed In-Network Storage (INS) schemes suffered from Storage Hot-Spots that are formed if either the sensors ’ locations are not uniformly distributed over the coverage area, or the distribution of sensor readings is not uniform over the range of possible reading values. Our K-D tree based Data-Centric Storage (KDDCS) scheme maintains the invariant that the storage of events is distributed reasonably uniformly among the sensors. KDDCS is composed of a set of distributed algorithms whose running time is within a poly-log factor of the diameter of the network. The number of messages any sensor has to send, as well as the bits in those messages, is poly-logarithmic in the number of sensors. Load balancing in KDDCS is based on defining and distributively solving a theoretical problem that we call the Weighted Split Median problem. In addition to analytical bounds on KDDCS individual algorithms, we provide experimental evidence of our scheme’s general efficiency, as well as its ability to avoid the formation of storage hot-spots of various sizes, unlike all previous INDCS schemes.

With the recent advances in Micro Electro-Mechanical Systems (MEMS) technology and wireless communications; the implementation of lowcost, lowpower, multifunctional sensor nodes that are small in size and communicate untethered in short distances has become feasible. The ever-increasing capabilities of these tiny sensor nodes enable the realization of wireless sensor networks (WSN) based on the collaborative effort of a large number of nodes. However, in order to realize the existing and envisioned applications and hence take the advantages of the potential gains of WSN necessitate effective communication protocols which can address the unique challenges posed by the WSN paradigm. Since the time these challenges had been been first pointed out in the literature, there has been a great deal of research effort focused on addressing them. Furthermore, the promising results of the research efforts since then have enabled the development and realization of practical sensor network deployment scenarios. In this paper, a survey of the applications, developed communication protocols, and real deployment scenarios proposed thus far for WSN is revisited. The objective of this survey revisit is to provide a contemporary look at the current state-of-the-art in WSN and discuss the still-open research issues in this field.

Abstract—This paper addresses the problem of survivability of many-to-one flows in wireless networks, such as wireless mesh networks (WMNs) and wireless sensor networks (WSNs). Traditional protection schemes are either resource-hungry like the (1+1) protection scheme, or introduce a delay and interrupt the network operation like the (1: N) protection scheme. In this paper, we present a network coding-based protection technique that overcomes the deficiencies of the traditional schemes. We derive and prove the necessary and sufficient conditions for our solution on a restricted network topology. Then we relax these connectivity requirements and show how to generalize the sufficient and necessary conditions to work with any other topology. We also show how to perform deterministic coding with {0,1} coefficients to achieve linear independence. Moreover, we discuss some of the practical considerations related to our approach. Specifically, we show how to adapt our solution when the network has a limited min-cut; we therefore define a more general problem that takes this constraint into account, which prove to be NP-complete. Furthermore, we discuss the decoding process at the sink, and show how to make use of our solution in the upstream communication (from sink to sources). We also study the effect of the proposed scheme on network performance. Finally, we consider the implementation of our approach when all network nodes have single transceivers, and we solve the problem through a greedy algorithm that constructs a feasible schedule for the transmissions from the sources.

Many applications developed for wireless sensor networks (WSNs) demand for Re-liable communication service, since majority of these applications are event-critical applications. There has been a vast body of knowledge on reliable data transfer in wireless networks; however, many of those solutions are not applicable to WSNs due to the fact that they address the problem by oering per message transport reliabil-ity. However, densely deployed sensor nodes can generate many redundant messages that essentially indicate the same event from the area of interest, this message-level reliability usually poses signicantly high and unnecessary communication costs. In this paper, we address the problem of reliable data transferring by rst dening event reliability and query reliability to match the unique characteristics of WSNs. Unlike other studies on transport protocols for WSN, we consider event delivery in conjunction with query delivery. For the purpose, we propose an energy-aware sensor classi cation algorithm to construct a network topology that is composed of sensors in providing desired level of event and query reliability. Using such an approach, reliability is granted in the sense that critical event reports are received by the sink
