Group Mobility Handover In Mobile WiMAX Network

Abstract

This paper presents Group mobility scenarios are that widely seen in military environment, emergency and
rescue activities. Group mobility refers to the scenarios that multiple mobile nodes (MNs) move in a group at the same
time, usually in the same direction with a small distance of separation. Some various challenges associated with group
mobility concept. In the group handover mechanism in WiMAX networks, initiation of the handover Proce ss at the same
time due to different users results in network congestion. So, when a group leader is introduced, it provides a solution for
this problem. Here, using RWPM(Random Way Point) and RPGM(Reference Point Group) model for measure the Qos
Parameter using VoIP applications various Services like BE, UGS, ertps, rtps and nrtps With Group Leader and
Without Group Leader network throughput, Average End to End Delay , Average Jitter and Packet delivery ratio. Also
measure the handover latency in the network.
