Location-Based Proactive Handoff Mechanism in Mobile Ad Hoc Network

Abstract

In mobile ad hoc network communication, one of the most important aspects is ensuring that a mobile station is connected continuously to the Zone Controller to ensure continuous and precise transmission of the node’s location, speed, and other relevant information. Due to the continuous motion of the node, handoffs between different APs are necessary to remain connected. This work proposes a location-based handoff method which will minimize handoff latency and provide better connections. The location-based handoff mechanism uses the concept of placing an access point (AP) at the predetermined locations. Handoff is triggered at the location where the AP (access point) is located and a connection is made to the new AP based on the channel information obtained. The architecture used in this scenario is WiMAX architecture and connections are maintained with the help of routers contained within the mobile stations. The proposed handoff method provides better handoff latency and error-free transmission in a system, where precise transmission information is necessary.
