Reliable and Energy-Efficient Routing Protocol for Wireless Sensor Network Liwei Tan
Abstract 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.

12.1 Introduction Routing protocol design is an important research area in wireless sensor networks, reliable, low-cost, and easy to maintain are design goals of WSN routing protocol, Single path routing algorithms in WSN focus on picking up an energy efficiency path from interconnect sensor nodes network, e.g., DD [1, 2], Minimum Cost Forwarding [3, 4]. They make sure data is transmitted on optimized path and

prolong the lifetime of the network. Besides energy efficiency, multipath routing take advantage of interconnect nodes network to enhance data throughput and packet delivery ratio. Hop-based routing protocol has been receiving extensive attention for its simple and effective design ideas. In WSN, both suddenly burst large amount of information and frequent event reporting will rapidly create shortage of resource (buffer space, energy) which leads to congestion and consequently packet drops. Congestion often happen in the middle or near the sink node of the network, it causes the reduction of node throughput and packet delivery ratio. It also increases time delay and energy wastage. Congestion control in WSN is particularly difficult as data is periodically collected in response to detected event. In Wireless Multimedia Sensor Networks (WMSN) [5, 6], video sensors are used to enhance the capability of event description [7]. Video sensors can generate image and video streaming data, which with heavy load require higher transmitting capability (bandwidth). Since high transmit rate is required for multimedia packages, congestion in WMSN is more prone to happen. So, congestion control is of prime importance in WMSN. The problem of congestion control has been addressed in many works, e.g., CODA, ESRT. They analyze how to
