The wireless sensor network (Wireless Sensor Networks, WSN) is a large-scale deployment of sensor nodes in the monitoring region formed by sensor nodes self-organizing dynamic network . This new technology combines wireless communication , a number of new technologies , embedded computing and sensor acquisition has a very high value in the modern military , agriculture , environment , e-commerce field . Wireless sensor networks with traditional communication networks , has its own characteristics , such as resource-constrained topology mutation and application related , which also presented new challenges because of these characteristics of wireless sensor networks . Since sensor nodes are generally unable to connect to a fixed power , usually carrying miniature battery - powered , which makes energy use to be severely restricted , so how reasonable , effective use of limited resources to extend the survival time of wireless sensor networks has become a hot research one of the problems . This paper the the energy efficient trusted routing protocol EERRP ( Energy Efficient Reliable Routing Protocol ) using an energy balancing strategy , Equilibrium energy consumption in the network , to maximize network life cycle ; introduction of the credibility of the evaluation mechanism , through a node in the data transmission process on the monitoring of the behavior of other nodes and reputation spread , so that the communication process in the data as much as possible to avoid the problem nodes to reach the destination node, to achieve reliable data transmission purposes . Through verification the NS simulation test platform on EERRP with , and is compared with the traditional routing protocols , prove EERRP has obvious advantages in terms of network energy efficiency and trusted data transmission . Constraints based on the conditions of the wireless sensor networks and demand , insufficient for LEACH protocol the father tree cluster routing layer based on immune algorithm to optimize the clustering stage , the network clustering more reasonable , balanced network energy consumption , making the network to maximize the life cycle . Comparison of the agreement with LEACH and immune algorithm to optimize the father tree routing by simulation software , to prove it has a better effect to extend the network lifetime and balanced energy consumption .
