Secured Dynamic Opportunistic Routing in Ad-hoc Wireless Network

In ad-hoc wireless network, the transmission efficiency decreases due to the restriction of channel interference, packet loss, and less bandwidth. Opportunistic routing (OR) is a new routing method which increases the network's efficiency. Though, most of the traditional OR solutions do not resolve the forwarder selection and routing overhead. To solve these issues, Opportunistic Routing for Dynamic Routing (ORDR) with security enhances the OR efficiency. This mechanism uses the mobile node authentication procedure to isolate the malicious nodes. The next transmitter node is selected energetically based on the link strength and the energy to the destination. Based on link quality, this approach discovers the best transmitter from the forwarder list. The proposed ORDR system measures link strength, received signal strength indication, and received packet rate. Experimental results illustrate that the ORDR mechanism provides the best efficiency compared to the baseline mechanisms in terms of delay and improves security.
