Performance Analysis of Handoff Algorithms for Multihop Ad Hoc Wireless Network

In this paper, performance analysis of handoff algorithms for multihop ad hoc wireless network has been performed. Handover algorithms considered here are based on relative signal strength measurements with hysteresis and combined signal strength measurements. Combined signal strength measurement includes both relative and absolute signal strength measurements. WLAN can be of infrastructure less type i.e., ad hoc type. In such a network, mobile station acts as a relay station in a multihop transmission. Mobile node (MN) has the ability to support base station functionality. In this paper, we considered Ad Hoc type wireless network with access point (AP) that can connect to wired LAN. Average number of handoff and average handoff delay are considered as performance metrics.
