A Survey on Vertical Handover Decision Framework In Heterogenious Wireless Networks

The wireless network of future will consists different radio access technologies. The transfer of mobile terminal\ud from one point to another point in an active communication needs a handover decision. Due to which vertical\ud handover decision will be a priority. The vertical handover decision can be based on different criteria such as\ud bandwidth, signal strength, cost etc., in order for network selection decision we use two algorithms such as\ud customer surplus value and fuzzy selection algorithm. Our goal is to develop a framework for efficient\ud simulation of VHO selection algorithm .This situation is on OmneT++ in various wireless networks
