....based on planar graph traversal [6] and limited flooding [2] Several real time protocols have been proposed for sensor networks. SWAN [1] uses feedback information from the MAC layer to regulate the transmission rate of non real time TCP traffic in order to sustain real time UDP traffic. RAP [9] uses velocity monotonic scheduling to prioritize real time traffic and enforces such prioritization through a differentiated MAC Layer. Woo and Culler [14] proposed an adaptive MAC layer rate control to achieve fairness among nodes with different distances to the base station. All of these ....

SWAN [4] uses feedback information from the MAC layer to regulate the transmission rate of non real time TCP traffic in order to sustain real time UDP traffic. RAP [66] uses velocity monotonic scheduling to prioritize realtime traffic and enforces such prioritization through a differentiated MAC Layer. Moreover, V.

....hand, the high density and large scale features of sensor networks give us an opportunity to achieve a predictable overall behavior through the aggregation among nodes. Since the control based methods are excel in converging the unpredictability into a desired performance, a lot of research [65][66][67] 90] 111] recently focuses on the approaches to model the target systems from the control perspective and applying standard control methods to regulate and guarantee system performances. In [65] C.Y.Lu etc. al. propose a framework for feedback based scheduling in which a low miss ratio of the ....

....behavior rendering static pre configuration utterly useless as network traffic, often initiated by environmental events of interest, transitions from one extreme to another. Several protocols have taken a first stab at addressing the need for adaptive behavior in such dynamic networks. RAP [23] and SPEED [t0] utilize locally available information to adjust priority levels or make more informed routing decisions in response to network congestion and changing traffic patterns. SPIN [13] makes adaptive decisions to participate in data dissemination based on current energy levels and the ....

....span all protocol stack layers, primarily motivated by a tighter interaction between the network and its physical environment. At the MAC layer, new protocols are needed that enforce message priorities consistently with time and distance constraints that arise from environmental interactions [22]. Awareness of the physical environment must also be incorporated into the network layer. For example, location should be an essential attribute of addressable networked objects [15] Location assisted routing protocols such as LAR [19] and DREAM [4] as well as location services [21] have been ....

....urgency, communicated among destinations that are different distances apart. The network has the responsibility of ordering these messages on the communication medium in a way that respects both time and distance constraints. A protocol that achieves this goal in our architecture is called RAP [22]. It supports a notion of packet velocity and implements velocity monotonic scheduling (VMS) as the default packet scheduling policy on the wireless medium. Observe that for a desired end to end latency bound to be met, an in transit packet must approach its destination at an average velocity ....

....the computing system. In particular, location awareness has been investigated at length. Starting with the network layer, location assisted routing protocols have received much attention such as LAR [22] and DREAM [3] A real time version of location based routing, called RAP, was introduced in [25]. For networks relying on identifier based routing, scalable location services have been proposed to keep track of locations of identified destinations [24] System prototypes have been developed in which location was an essential attribute of system objects [16] The aforementioned protocols are ....

....complementary to our work. Recently, research has started to address QoS issues to support differentiated services for sensor networks. SWAN [1] uses feedback information from the MAC layer to regulate the transmission rate of non real time traffic in order to sustain real time traffic. RAP [17] uses velocity monotonic scheduling to prioritize real time traffic and enforces such prioritization through a differentiated MAC Layer. In [2] the delivery ratios of packets at different priority levels are affected by the forwarding probability at intermediate nodes. To date, to the best of ....
