Performance evaluation and QoS analysis of PDCH and MBC routing protocols in wireless sensor networks

This paper focuses on variants of PEGASIS and CBR routing protocols, PDCH and MBC, which are decedents of Hierarchical routing protocols. Hierarchical routing protocols are best known for energy efficiency. PDCH is a routing protocol with double cluster head. It elects its cluster head based on the distance from base station. In MBC the cluster head is selected based on the residual energy and mobility. A non-cluster head has to transmit data before its transmission power is finised to the cluater head so with in the TDMA schedule data should be send. Here simulation were conducted in NS2 Software. The QoS parameters that were compared were Delay, Throughput, Packet drop ratio and Energy consumed. From the simulation it was clear that PDCH outperformed MBC by 15.13%, 4.87%, 14.29% and 23.19% for the above parameters.
