Review on SME Routing Protocol for Asymmetric Wireless Network

Asymmetric Wireless sensor network is dynamic in nature and completely operates on infrastructure less environment. It discovers way routes dynamically to reach the destination. Securing a dynamic way route which is not known in before communication is always a challenge. Energy conservation and finding the shortest path is a key challenge. This paper presents design of a shortest path Minimum Broadcast Energy conserving (SME) Protocol for Asymmetric Wireless Sensor Network. It finds the shortest path in minimum broadcasts and conserves energy in asymmetric wireless network. The basic idea behind SME is to improve upon RP, Layhet, Egyhet from the state of the art and achieve performance enhancement with better delivery rate consuming minimum energy and slow sinking with reduction in energy during data routing process for data transmission to destination for the way route selected in an asymmetric environment. Asymmetric indicates where two end nodes may not use the same path to communicate with each other. The state of the art had proposed a performance guaranteed protocol achieving the above desirables. We want to improve upon the achievable with our novel SME protocol. A comparative study will be carried out to demonstrate the performance of our strategy over the RP framework from the state of the art.
