An Overview of the Existing Routing Protocols and Trust Based Algorithms in Mobile Ad-hoc Networks

Mobile Ad-hoc NETwork (MANET) is a temporary network that can be dynamically formed to exchange information by wireless hosts which may be mobile. The network is ad hoc because it does not rely on any pre-existing network infrastructure like routers in wired networks. The devices in a MANET can communicate with each other without the help of any centralized administrator. Such networks have no fixed topology because of the high degree of node mobility. The nodes in a MANET sometimes act as routers to forward packets to each other.
