Wave Dissemination for Wireless Sensor Networks

摘要

Wireless sensor networks consist of a large number of the distributed nodes organized in a multihop structure. Energy consumption in sensor nodes that are generally battery-operated is very important. This paper proposes an energy efficient routing/MAC integrated scheme, called Wave Dissemination, to prolong the network lifetime by having all nodes uniformly consume their energies without increasing delay and degrading throughput. Wave dissemination scheme generates the virtual wave lines that induce the wave-to-wave networking. Wave dissemination consists of three network phases: network initialization, query wave and data wave. Simulation study assures that wave dissemination scheme outperforms the traditional protocols; it achieves a higher energy saving and a lower message delay.
