Extended buffer zone algorithm to reduce rerouting time in biotelemetry systems using sensing

Abstract

Mobile Adhoc Network (MANET) routing methods must deal with connection breakdowns caused by frequent node movement, measurement and a dynamic network topology. In these cases, the protocol must discover alternate routes. Rerouting time refers to the lag that happens during this retransmission. Researchers have proposed many ways to reduce rerouting period. One such technique is buffer zone routing (BZR), which divides a node transmission region into a safe zone adjacent to the node and a hazardous zone towards the end of the broadcast range. This technique, however, has rare gaps and restrictions, such as the ideal dimensions of the buffer zone, a rise in hop duration, network stress, and so on. This study offers a method to improve or expand buffer zone communication by grouping nodes inside the buffer zone into virtual zones based on their energy flat. When the routing decisions are made quickly, the energy consumption of the nodes is minimized. In the safe area of extended BZR, transfer time is reduced, and routing efficiency is increased. It solves issues in the present algorithm and fills holes in it, decreasing the time required for rerouting in MANET.
