Study and Development Secure Subnet Gateway Routing Protocol for MANET

Abstract

MANET is a decentralized distributed network. Generally the networks like the infrastructureless network. MANET has no need of base station, router and modem, while communication is newlineachieved by multi-hop wireless links in dynamic networks and the mobile node acts as the router. newlineThese mobile nodes are communicated to other nodes using their radio range. MANET is more newlineused where without the infrastructure-based network like, the transmission of the packet in the newlinemountain, desert, and communication at the time of earthquake etc. MANET is also used for the newlinerescue operation and environmental monitoring. Many researchers had proposed a protocols newlinemechanism. These proposed algorithms have described the mechanism for finding the path in newlinedynamic nodes in MANET. newlineThe focus of this research is to try to achieve high speed during the updating route discovery, newlineinformation maintenance and select the path which is minimum congested, minimum operating newlineexpense and minimum power use in variable network topology. At this stage nodes are movable newlineand network topology changes spontaneously, then finding the route in MANET is difficult and newlineconsume maximum battery power because the node functioning totally depends upon nodes newlinebattery. Thus for discovery of routes maximum power is consume reducing the network newlinelifetime. Further the security issue is also challenging because due to this attacker probability newlineincreases. So, we have reported proposed a protocol mechanism in this dissertation. After doing newlinestudy of existing routing protocol, and modifying an existing routing mechanism by proposing newlineAdaptive Hybrid Subnet mechanism. By proposed changes to the existing model, network newlineperformance is expected to reduce packet drop and conserving more energy while keeping the newlineoptimum throughput. Further, we propose Adaptive Energy efficient algorithm and secure newlineEvidence transmission algorithm to enhance the network lifetime and secure communication in newlinemobile ad hoc networks. newline
