Bio-Inspired and Trust Based Clustering Routing Protocol For Hybrid MANETs

Hybrid wireless networks are a combination of traditional fixed-network systems and mobile ad hoc networks. They are used in various applications such as online classes, video conference meetings, rescue operations during natural catastrophes, military engagements, and battlefield operations. One of the most challenging problems in a dynamic connectionless environment such as MANET is ensuring secure transmission. Another important challenge is maximising network lifespan by optimising energy consumption. In order to address the aforementioned concerns, we propose the utilisation of a clustering routing system for hybrid wireless networks that is both energy efficient and based on trust. This protocol incorporates particle swarm optimisation and Fuzzy logic for its implementation. The system constructs a cluster by selecting and designating the cluster head and super cluster head nodes. Secure transmission involves evaluating trust factors for each node and calculating a trust value. Multiple secure paths are then generated from the source to the destination. The path with the highest trust value and the greatest bandwidth is chosen for the transmission. The experimental investigation of the proposed BT-CPHM protocol demonstrates a decrease in delay, power consumption, packet drop, and an improvement in throughput and network longevity.
