Abstract |
The UAV Communication Networks (UAVCN) comes under the umbrella of Ad hoc Network technology. It has the key differences with existing wireless networks, which are the high mobility, high speed, dynamic updates and changes in topology due to high movement which creates problem of link breakages and affects the routing performance. This problem decrades the performance of UAVCN in terms it decreases throughput and minimizes the packet delivery ratio. In this paper we have tried to overcome this problem by considering the received signal power strength (RSPS). We have proposed an algorithm which uses the received signal power strength and time and calculates the link breake time by using the interpolation method. We have implemented proposed technique by modifying the protocol OLSR. The extended protocol term as EPOLSR which efficiently using the signal power strength and time and increasing the performance of UAVCN. The extended protocol implemented by using research tool network simulator (v3). The metrics received rate , no of received packets, throughput and packet delivery ratio (PDR) is considered for evaluation. We have examined the proposed EPOLSR with existing routing protocols. It has been observed that modified protocol performs better with respect to all existing evaluated routing approaches. |
