RETRACTED ARTICLE: A reliable multi-hop opportunistic routing scheme with bandwidth guarantee for multimedia wireless mesh networks

Abstract

Opportunistic routing (OR) is a novel challenging idea that has been designed for the wireless mesh network (WMN). This routing strategy captured the attention of numerous researchers due to its intense performance encountered in WMN. Broadcast characteristics of OR lead to performance enhancement in WMN. It possesses the ability to overhear packet transmission and accomplishing coordination between the relay nodes. In this paper, a reliable opportunistic routing scheme with bandwidth guarantee for multimedia wireless mesh networks (RORBG) scheme for multimedia WMN is proposed. This strategy is capable of recognizing various attacks like a black hole, grey hole, and denial of service attacks proficiently. The important pertains to treat the overhead and the latency of transmitting the data packet. In this scheme, we establish a node honesty rate to distinguish malicious behaviour and give assurance bandwidth. The expected available bandwidth (EAB) is computed by the local available bandwidth. Moreover, the forwarder candidate node is selected based on the bandwidth as well as the communication quality factor. This scheme grants to attain forwarder candidate selection procedure and coordination methods are a helping to improve the WMN execution along with efficient packet delivery. The application of RORBG is army and traffic management. The simulation results illustrate that RORBG scheme increases the 12.17% throughput and 16.81% delay minimization compare to the baseline routing protocols in WMN.
