Reliable and Energy-Efficient Routing Protocol for Wireless Sensor Network

摘要

This paper gives hop based routing protocol a detailed analysis, then a new routing policy-Reliable and Energy-efficient Routing Protocol for WSN (REERP) is proposed. In data transmission phase, REERP makes parents and siblings as forward selection; relying on a formula for evaluating the routing quality, routing mechanism has a comprehensive consideration of the forward selection; trigger update mechanism is used to maintain dynamic network topology and avoid "routing hole"; data packets act as a part of routing packets, which can reduce network maintenance cost. Compared with, DD, join-MHC in omnet ++ simulation tool, REERP proves its strength in load balancing, congestion avoidance, extending network lifetime, reliability, and low routing overhead.
