For this purpose, WSN must has different protocol to process different tasks, for example, route protocol, Mac protocol, transport protocol ..... etc. Because WSN usually uses battery for power supply, and difficult to recharge or to replace, therefore, the power consumption is a most important issue in WSN. Routing protocol is building a forwarding path between the sink and source for data transmission. When we try to find a path, if only concerning any single condition, like reliability, delay or another, then it maybe lead to use some sensor node too frequency and make these nodes deplete their energy too quickly then dead. Routing protocol also must has solution to face transmission path broken maked by node dead. This paper introduce IRER(An Improvement on Reliable Energy Aware Routing in Wireless Sensor Networks), through distinguish the “available energy” and the “remaining energy”, to make different path can distributed on different node set and further to balance power consumption on each node. IRER also attempts to restrain the frequency of reRoute by local repair then economizes the power consumption.
