RRDD: Receiver-oriented robust data delivery in mobile sensor networks

Data forwarding in the wireless networks typically employs a sender-oriented approach in which the next hop node is pre-selected based on neighbor or network information. This method incurs large overhead when accurate information is needed for making the optimal forwarding decision. In this paper, a receiver-oriented robust data delivery scheme (RRDD) is proposed for mobile sensor networks. In RRDD, the sender does not appoint a specific forwarder proactively, but allows its neighboring candidates to dynamically contend for the data forwarding task based on local state information. In this way, the best-suited node is elected at each hop to provide robust and efficient delivery service to data packets. Comprehensive simulations show that RRDD exhibits superior transmission performance over all of the compared schemes.
