Abstract

The most important technology we must concentrate on in the different application fields of WSN is health applications and the transmission reliability of health data in multi-hop communication. Short-term health signal failure may be fatal or life-threatening. The topology of an ad hoc network changes regularly due to the node movement and communication in those scenarios depend on the path selected for transfer of information. Since all the nodes are battery-powered, energy-efficient routing should be provided to extend the network's life. In MANET's critical issues include energy usage, QoS (Quality of Services), vulnerability to attacks, and connection stability. Link stability is a topic that needs to be addressed in order to improve communication. Since radio links are generally varied due to node mobility, Link Stability is important to extend the life time. This work gives comparison of three existing multicasting routing protocols that can be used in health monitoring systems. MAODV, LSP-MAODV and PN-SEMRP are compared using NS2 simulation. PN-SEMRP shows better results when compared to the other mechanisms
