摘要
Abstract
Wireless sensor networks usually adopt low duty-cycle asynchronous sleep schedule to reduce energy consumption of node. Since a sender can’ t send data packet until the receiver wakes up,additional waiting delay will be introduced. In some recent anycast routing schemes,a sender dynamically selects the first candidate to wake up to forward data packet,in order to minimize the waiting delay. However,the de-lay from the first candidate to the base station may not be low,so anycast routing can not necessarily mini-mize the total end-to-end delay. For this problem,an opportunistic routing scheme is proposed for asyn-chronous wireless sensor networks, where routing decision is modeled as a strong-Markov process and a simplified stopping rule of this process is derived through optimal stopping theory. Simulation results show that the maximal end-to-end delay from the sender to the base station is only 68 . 5% of the opportunistic routing based on geographical location.关键词
