Mobility Management with OLSR Protocol for Fourth Generation (4G) Mobile Networks

Trends in fourth generation (4G) wireless networks are clearly identified by the full-IP concept where all traffic (data, control, voice and video services,etc.) will be transported in IP packets. Many proposals are being made to enhance IP with the functionalities necessary to manage the mobility of nodes, so that networks can provide global seamless roaming between heterogeneous wireless and wired networks. OLSR (Optimized Link State Routing) is that way for IPv6 management, this cause of reduction of overhead and recovery routing. OLSR for adhoc networks with fast nodes have poor efficiency. therefore kind of OLSR that named fast-OLSR is perposed. In this paper, we propose implementation of fast-OLSR for improvement efficiency of fourh generation (4G) mobile networks. In this implementation, use IP protocol for macro-mobility management and for micro-mobility use fast-OLSR to manage mobility. Efficiency evaluation show that loss rate proportion of use OLSR is decrease. As a result increase reliability of services.
