Evaluation of Traffic Delay and Resources Utilization in Wlan Handover Schemes
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2018, Vol 13, Issue 5
Abstract
Wireless local area networks (WLAN) have seen rapid growth making it very popular and widely used in data communication. New technologies in WLAN provide high data rates for real time services and also support multimedia applications such as voice over IP and e-conference. Critical to the 802.11 MAC operations, is the handover function which occurs when a mobile node moves its association from one access point (AP) to another. Unreliable and insufficient handover procedure reduces the quality and reliability of the network. Two handover schemes: proactive scanning handover scheme (PAHS) and prevent scanning handover scheme (PRHS) were selected for comparative evaluation. Specifically, the comparison was based on the following quality of service (QoS) indicators: handover delay and resource utilization. Results show that at traffic intensity of 2401615, PRHS and PAHS experienced delays of 1.47e-06 and 1.69e-06 respectively while at traffic intensity of 969470, resource utilization for PRHS and PAHS are 5.74e-02 and 7.01e-02 respectively. PRHS algorithm, therefore, performs a more efficient and seamless handover process in terms of reduced delay while the PAHS offers greater resource utilization at every level of traffic intensity.
