摘要：Wireless sensor networks have become increasingly popular due to their wide range of applications.Energy consumption is one of the biggest constraints of the wireless sensor node and this limitation combined with atypical deployment of large number of nodes has added many challenges to the design and management of wirelesssensor networks. At high temperature the transmission power and sensitivity will decrease which leads to thedegradation of wireless links. To avoid that we have implemented a hybrid routing protocol: Zonal-Stable ElectionProtocol (Z-SEP) for heterogeneous WSNs. In this protocol, some nodes transmit data directly to base station whilesome use clustering technique to send data to base station as in SEP. We implemented Z-SEP and compared it withtraditional Low Energy Adaptive Clustering Hierarchy (LEACH) and SEP. In addition, that energy can be optimized byscheduling the node to sleep mode and alive mode. Simulation results showed that Z-SEP enhanced the stability periodand throughput than existing protocols like LEACH and SEP.
