Abstract

In wireless environments, congestion and link error can cause packets to be lost. Thesetwo factors are reducing the end-to-end reliability and energy efficiency. These problems can be overcome by recovering lost packets using retransmission. Since the delay is highin the end-to-end retransmissions, we are looking for a way to reduce this delay. Hop-by-hop transmission and buffering packet in some special intermediate nodes, where they can be retransmitted for another time can be a solution. In this paper, loss recoverymechanism with lost packets of data storage is proposed by using the RRR algorithm inwireless sensor networks (CRRR).

Key words: Wireless sensor network, randomized re-routing algorithm.
