Wireless sensor networks are comprised of a vast number of ultra-small, fully autonomous computing, communication and sensing devices, with very restricted energy and computing capabilities, that co-operate to accomplish a large sensing task. The efficient and robust realization of such large, highly-dynamic and complex networking environments is a challenging algorithmic and technological task.
In this work we present and discuss two protocols for efficient and robust data propagation in wireless sensor networks: LTP (a “local target” optimization protocol) and PFR (a multi-path probabilistic forwarding protocol). Furthermore, we present the NanoPeers architecture paradigm, a peer-to-peer network of lightweight devices, lacking all or most of the capabilities of their computer-world counterparts. We identify the problems arising when applying current routing and searching methods to this nano-world, and present some initial solutions, using a case study of a sensor network instance; Smart Dust.
