Abstract: The latest advancements in wireless communication are more emphasis on delivering sensitive info to destination node under several constraints such as latency ,energy, reliability, stability, and security. So there is rise of Wireless Sensor Network Technology[1] .Though it is possible to assimilate sensing and computing units along with transceiver(transmitter & receiver) and power supply to a single entity called as Sensor Node (SN). The combination of SNs constitute a type of network known as Wireless Sensor Networks (WSNs)[1]. Several researched proposals on WSNs have mainly emphasis on energy minimization of the Base Station (BS) for communication process. Although clustering is the most well-known technique for the enrichment of network lifetime by effective energy utilization of sensor node, but heterogeneity issue of sensor node is another interesting aspect which can be considered to save the energy consumption of sensor nodes in the network field. Mobility Issue is also one of the major aspect in determining performance of the network . In this paper considering all these issues, , we have tried our best to categorized different heterogeneous routing protocols for WSNs based upon some predefined parameters .Different performance evaluation metrics such as- network lifetime, Number of Heterogeneity Level, Cluster Head Selection(CHSelection), Energy Efficiency, Stability and Mobility. The extensive categorization gives insights to various readers to select one of the protocols from various categories based upon its advantage over the others.

Keywords: Heterogeneity, Cluster Head Selection, Mobility, Heterogeneous Routing Protocol, Threshold Value.
