Abstract
Existence obstacles in terrain area and the mobility of the nodes in the network are the vital constrains that degrade the performance in Mobile Adhoc Network (MANET). To diminish the effect of such obstacles and mobility on the performance of MANET, the protocol used for routing must be efficient enough to handle both the factors. In the present work, we have considered the issues of Mobility and obstacle aware multipath communication in MANET. For avoiding obstacles, DeCasteljau Algorithm with Bezier curve concept has been applied. To the minimize impact of mobility, a speed based mobility prediction concept is used. Here optimal routing path across the obstacle is selected depending on its mobility prediction indicator, link duration, network connectivity and path availability. The performance of the suggested protocol is evaluated with Network Simulator-2. Simulation results confirm that the suggested protocol minimizes average energy consumption, network overhead, average delay and improves data deliverance in MANET.
Highlights
Mobile Adhoc Network (MANET) is established with the help of a number of mobile communicating devices without having a centralized infrastructure
Many researchers have taken the geographic characteristics and the presence obstacles in their work, but nobody has suggested a protocol that addresses both obstacle and mobility issues in simulation terrain with the existence of irregular shape obstructing objects. In this part of work, we have proposed and analyzed a Mobility and Obstacleaware Algorithm for optimal MANET Routing (MOAR)
We have developed a simple and effective algorithm to overcome the presence of seven real world polygonal obstacles
