Enhanced Stability Routing Scheme against Radio Jamming Based on NDL in Multi-hop Wireless Networks

Most of the routing protocols for wireless networks have focused on finding a feasible route from a source to a destination. Routing Protocols in Multi-hop Wireless Networks (MHWNs) face more serious security and reliability challenges. Radio jamming attacks are especially harmful to the reliability of links, as they can effectively disrupt communication between any node pairs result in that links are continuously created and broken. Selecting a long lasting and steady-going route in multi-hop wireless network is a critical task. This paper studies the impact of jamming on the common protocols of wireless networks and presents an improved reliable AODV routing protocolbased on Neighbor Dependency Level(NDL)which named as RPBND protocol. The NDL of a node and its neighbor is divided into three ranks, that is, fully-dependent, half-dependent and independent level. Then, route selection ways for different NDL are presented, and different priorities of the neighbor nodes with different NDL to be selected as the next hop node are assigned. The performance of the stable routing protocol based on Neighbor Dependency Level (NDL) is demonstrated in simulation, and compared with the traditional Min-hop-based AODV routing algorithm and the improved Cost-based AODV routing algorithm. The simulation results show that the RPBND protocol has better data transmission stability.
