Mobile ad hoc network(MANET)is a centerless packet radio network which does not use fixed infrastructure.It has recently received tremendous attention due to its capabilities of self-configuration and self-maintenance.However,attenuation and interference caused by node mobility and wireless channel sharing weaken the stability of communication links.A mathematical exploring model for the next hop has been established based on the optimal exploring theory.The negative impact of wireless routes discontinuity has been alleviated by a novel fast local routing repair scheme(FLRRS)proposed in this paper,wherein the route requirement zone has been restricted into a pie slice region on intermediate nodes according to the solution of exploring equations.The scheme is an effective approach in reducing the average end-to-end delay during routing maintenance.It also allows continuous packet forwarding for fault resilience.NS-2 based simulation results showed remarkable successful packet delivery rate and end-to-end delay improvements of source-initiated routing protocol with the fast local repair scheme,especially in the case of high dynamic environments with heavy traffc loads.
Mobile has recently received tremendous attention due to its capabilities of self-configuration and self-maintenance. However, attenuation and interference caused by node mobility and wireless channel sharing weaken the stability of communication links. A mathematical exploring model for the next hop has been established based on the optimal exploring theory. The negative impact of wireless routes discontinuity has been alleviated by a novel fast local routing repair scheme (FLRRS) proposed in this paper, the route requirement zone has been restricted into a pie slice region on intermediate nodes according to the solution of exploring the equations. The scheme is an effective approach in reducing the average end-to-end delay during routing maintenance. It also allows continuous packet forwarding for fault resilience. NS-2 based simulation results showed remarkable successful packet delivery r ate and end-to-end delay improvements of source-initiated routing protocol with the fast local repair scheme, especially in the case of high dynamic environments with heavy traffc loads.
