....two party data authentication, and data freshness, with low overhead. Designing and developing an authenticated routing protocol using SPINS building blocks 1. 1 Sensor Hardware At UC Berkeley, we are building prototype networks of small sensor devices under the SmartDust program [32]. We ve deployed these in one of our EECS buildings, Cory Hall (see Figure 1) By design, these sensors are inexpensive, low power devices. As a result, they have limited computational and communication resources. The sensors form a self organizing wireless network and form a multihop routing ....

....and aggregation, and reputation, within such a mechanism, and propose a straw man model. 1 Introduction We are at the frontier of a world of pervasive computing, with fast, cheap, and small computational devices everywhere. Devices are embedded in buildings and physical infrastructure [17, 13], mobile devices continue to get smaller and more powerful, and ad hoc wireless networks continue to emerge. As pervasive computing blurs the boundary between the physical and the virtual, we become perpetual users of a massive and decentralized computational system. It will soon be possible to ....

....packages. Additionally, advances in CMOS processing and MEMS research make it possible to construct a low cost networked sensor. In the near future, researchers predict that it will be possible to integrate communication, power sources, sensors and actuators with computational elements in a mm [11]. Energy stored within each networked sensor is the most precious resource, so both the hardware architecture and the software system should be optimized for its usage. Each sensor has a limited energy source, and replenishing this energy source may be either impossible (no physical access to the ....

They show 2 6x energy improvement when compared to standard 801.11 like wireless networking protocols [20] They have also generated optimized routing protocols designed to conserve energy in deployed networks[21, 22] The Smart Dust[23, 24] project at UC Berkeley is investing the use of application specific hardware for the development of dust sized sensor devices. In targeting extreme miniaturization and low power consumption they are putting as much functionality as possible into special purpose hardware. They include a tiny ....

Particularly, multi hop routing applications need the ability to have low power intermediated nodes forward data on behalf of other nodes. IX. RELATED WORK On the hardware side, the Smart Dust Project [19] is developing a millimeter cubed integrated network sensor. There is also work in developing low power hardware to support the streaming of sensor readings over wireless communication channels [5] However, both of these systems have focused on the enabling hardware rather than on the programming ....

A system would have to assign not only a task, This assumption might be reasonable in the light of modern technology [19] but also combine robots in a group if a task requires participation of several robots.

....they are used less than one might expect. One reason is that known techniques for traversal of trees require a relatively large amount of computation, storage, or both. Such constraints make all but the smallest trees impractical, and in particular not very useful for small and powerless devices [11]. Our Contribution. We propose a technique for traversal of Merkle trees which is structurally very simple and allows for various tradeo#s between storage and computation. For one choice of parameters, the total space required is bounded by 1.5 log N loglog N hash values, and the worstcase ....

....results obtained in [10] are about one order of magnitude. In addition, it is shown in [10] that if the number k of available markers reduces, the cover time increases rapidly. Therefore, in dynamic environments Note that this assumption might be reasonable in the light of modern technology [17] the performance of the algorithm decreases drastically even if one marker is destroyed. Whereas in our algorithm such a problem does not exist, since a new marker will be deployed in place of the destroyed one automatically. We verified the performance of our algorithm and its asymptotic ....

....sensor devices, and to small transceiver chips. One such sensor is described in this study. Many researchers envision driving this networked sensor platform down into microscopic scales by integrating communication, computation and micro electrical mechanical (MEMS) devices onto a single chip [5, 45]. These networked sensors will be integrated into their physical environment, perhaps even powered by ambient energy [34] They will be used in many smart space scenarios. As these devices are deployed in large numbers, they will need the ability to assist each other to communicate data back to a ....

The extreme constraints of these devices makes it impractical to use legacy systems. Other research projects [5, 45] are advancing the physical hardware technology that is enabling these devices. We provide an initial exploration of software architectures for networked sensors. Our investigation is grounded in a prototype current generation device constructed from o# the shelf components. We have developed a ....
