After review of literature, most of the work is done on handoff between cellular network, i.e., horizontal handoff but, few papers are on handoff between heterogeneous networks are in existence. This type of handoff called as vertical handoff can be simulated. The current problem in handoff makes the system slow and hence increases the latency in the system. In this paper a novel technique based on encryption and dual compression for transferring handoff data between mobile station and base station. Which will increases the speed and security during handoff thus increasing the throughput and reducing the latency of the system.
