Abstract :
Reliability, Power efficiency and Delay are critical issues in Wireless Sensor Networks. In this work, we developed a framework for Power-Control and Delay-aware routing and MAC protocol (PCDARM) for Energy constraint and delay sensitive wireless sensor network applications. This framework aims to route the packets along multiple paths with the delay that is known earlier and with energy and link reliability constraints, in the routing phase and TDMA based slot assignment in power efficient manner in MAC phase. The design in routing phase uses the splitting of traffic along multiple paths. It considers differential delay, link reliability and energy constraints in wireless sensor networks. In MAC phase, slot allocation in TDMA frames with sleep and wake-up cycles for the nodes of the network results in efficient power control. We present numerical results considering the advantage of our protocol over DEAR. Simulation results shows that the delay experienced by the packets is less in PCDARM and also outperforms in terms of energy consumption.
