In this paper, we study a wireless sensor network (WSN) as a social network in which the embedded sensors are the main entities as opposed to human beings in a traditional social network. In wireless sensor networks, the nodes resemble individuals in a way that they communicate with their peers, sometimes selectively hiding some information, sometimes selectively exposing some other information, generating...
We propose partial and full link reversal algorithms to bypass voids during geographic routing over duty-cycled wireless sensor networks. We propose a distributed approach that is oblivious to one-hop neighbor information. Upon termination of the algorithm, the resulting network is guaranteed to be destination-oriented. Further, to reduce the delays incurred under reactive link reversal, we propose...
One of the challenging issue in wireless sensor networks (WSNs) is efficiently route the multimedia information. In this letter, we propose an efficient geographic routing algorithm for multimedia data transmission such as audio, video, etc., in WSNs. It finds one near to shortest path per iteration and can be performed repeatedly iteration to find more on-demand shortest node-disjoint routing paths...
Maximizing the lifetime of wireless sensor networks under constrained resources is an interesting problem that has gained increasing attention. Most methods assume an ideal link layer model when increasing the lifetime of wireless sensor networks and energy saving techniques using geographic routing remains largely unexplored. Based on a realistic link layer model, we propose a novel geographic routing...
Energy-aware routing is important in multi-hop wireless networks that are operated by battery power, e.g., wireless sensor networks. To maximize the network survivability, the energy efficiency of paths must be taken into account for route selection. Simple heuristics such as choosing paths with minimal energy consumption do not perform well, because the energy of the nodes on such paths may deplete...
