Abstract
Wireless Sensor Networks (WSNs) is always paid attention to by researchers. Power dissipation of a node is an important quota in WSNs. It influences the network lifetime. For extending the lifetime of WSNs researchers used many methods to save the energy of nodes. For example the energy of nodes was saved by reducing the amount of transmission data by means of data fusion. Another content which is usually researched to save the energy of nodes was routing protocol. This paper presented Small Overhead Routing Protocol (SORP) to increase the efficiency of transmission which could prolong the lifetime of nodes of WSNs while its’ amount is less than 254. And the minimum residual energy was treated as a key factor to decide the routing table together with hop count. It could avoid some nodes which were often used to relay message die much faster than the other nodes. The simulation results show that SORP could prolong the lifetime of most node in the network.
