Operating Network Load Balancing with the Media Independent Information Service for Vehicular Based Systems
نویسندگان
چکیده
A mechanism is designed here to realize Network_Load_Balancing (NLB) by directing handover based on Media Independent Handover for vehicular based systems. We designed a Predictive_Link_Going_Down event based on Media Independent Event Service which accurately estimates the performance degradation to predict vehicle movements and a Predictive_Handover_Information_Structure (PHIS) based on Media Independent Information Service. This includes the network geographical information, MN’s moving information and network loading situation. PHIS is sent to upper layer mobility protocol dynamically as input for NLB operation, which utilizes a MN direction fuzzy logic to consider both the vehicle movement prediction and current network loading situation and Optimal Candidate Base Station Selection, which utilizes the fuzzy MADM algorithm. Results illustrate the proposed approach reduces more than 95% handover duration in comparison to without utilizing any link triggers. With the NLB operation, delay is reduced by 1ms and jitter is nearly closed to 0, thus significantly improving QoS. KeywordsMIH, IEEE 802.21, Handover, Fuzzy MADM, Network Load Balancing
