A survey of routing protocols in Wireless Sensor Networks: Hierarchical routing

摘要

Wireless Sensor Networks (WSNs) is the most developing areas in many factors like environment & wildlife monitoring, security & military surveillance, healthcare and many more. Also, routing protocols play a very important part in terms of efficiency in WSNs. Due to limitations of unreliable low power links and resources between the sensor nodes; design of an efficient routing protocol is a difficult problem. This paper has surveyed about Routing Techniques and basically about Hierarchical based routing with its protocols like LEACH, TEEN, PEGASIS, SEP and DEEC. And then finally their comparative study is provided.
