CARING SYSTEM FOR ELDER PEOPLE

Mobile Ad-hoc Networks (MANETs) is self-configured and decentralized wireless network without any prior infrastructure. Every node in it acts as a router as well as end system and hence each node in MANET is allowed to move freely which makes routing difficult. Most of the MANET routing algorithms like AODV and DSR assume that every node will forward every packet it receives. In opportunistic routing, a node selects and prioritizes multiple nodes which can act as potential packet forwarders. Source node will relay packets to the destination node through the intermediate node. However, misbehavior of the selfish nodes is a common phenomenon in MANET. These nodes use the network and its services and do not provide any services to intermediate nodes in order to save energy such as battery, CPU Power and bandwidth for relaying data from other nodes and reserve for themselves. These selfish nodes will degrade the performances of wireless ad hoc networks. In this thesis, Using OR and BPR routing protocols to overcome the presence of selfish nodes and also BPR routing protocol used to avoid malicious nodes. These protocols used to avoid congestion and perform the simulation using Network Simulator.
