Performance analysis of genetic zone routing protocol combined with vertical handover algorithm for 3G-WiFi offload

In the deployment scenario of multiple base stations there is usually a deficiency in the routing protocols for load balancing in the wireless network. in this study,we propose a routing algorithm that can be implemented inmobile adhoc networks (manets) as well as third-generation (3g)-wireless fidelity (wifi) offload networks. we combined the genetic zone routing protocol (gzrp) with the vertical handover (vho) algorithm in a 3g-wifi offload network with multiple base stations. simulation results show that the proposed algorithm yields improvement in the received signal strength (which is increased up to 25 dbm),user throughput (which is approximately 1 mbps-2.5 mbps),and data rate (which is increased up to 2.5 mbps). © 2014 published by itb journal publisher.
