One of the recent trends in wireless networking is Wireless sensor network (WSN), in this type of network tiny electronic device sensors organized in an environment where human intervention is problematic. In WSN, various sensors organized in a sensing environment works together in coordination to monitor and control the physical property of an environment. To efficiently perform the given task while keeping the longer network lifetime, WSN requires Energy efficient routing protocol. In this paper two hierarchical routing protocols ECHERP (Equalized Cluster Head Election Routing Protocol) and PDCH (PEGASIS with Double Cluster head) has been discussed and performance of both the protocols is analyzed based on various QoS parameters like Delay, Throughput, Packet Drop Ratio and Energy consumption.
