In wireless network, mobile nodes frequently perform layer 2 and layer 3 handoffs. The handoff may occur due to many factors like signal strength, load balancing, number of connections and frequencies engaged...etc. This frequent handoff may disturb the services of real-time applications such as voice over IP. Normally few milliseconds of interrupt will happen during the handoff process. This delay should be minimized for smooth performance. Information exchange between mobile nodes and network monitoring has to be done to achieve seamless layer 2 and layer 3 handoff. Increasing in packet loss rates and heavy traffic will initiate incorrect handoff. We propose a method for avoiding unbeneficial handoffs and to eliminate unwanted traffic.
