A Survey on Geographical Opportunistic Routing Protocols in Wireless Senor Networks
Abstract
Geographical Opportunistic Routing (GOR) becoming a promising approach to achieve network lifetime enhancement and soft quality of service requirements in Wireless Sensor Networks (WSNs). It has been a hot topic of research. Typically, A Geographical Opportunistic Routing is called geographical position-based routing, in which routing decision depends upon the geographical location of the sender and the sink. The owing capability of fulfilling various wireless network requirements, Geographical Opportunistic Routing is becoming an active branch of routing technology in WSNs. In this paper, a survey on existing Geographical Opportunistic Routing protocols for WSNs has been done. We have also proposed a taxonomy to classify Geographical Opportunistic Routing protocols based on their objective of proposal. Additionally, a few most popular Geographical Opportunistic Routing Protocols are discussed and their comparative study is presented based on some primary metrics. In the end, the research scope in the area of Geographical Opportunistic Routing has been discussed.
