Abstract: “In wireless networks, due to limited battery power, it is crucial to reduce the transmission overhead and power consumption. In this paper we discuss how to achieve low transmission overhead and reduced power consumption by minimizing the transmission of redundant control messages. The popular on-demand multi cast routing protocols like AODV and ODMRP has drawbacks due to transmission overhead. As the mobility of communicating nodes increases the transmission overhead also increases as the numbe”
