Next generation wireless networks are expected to integrate and coordinate heterogeneous communication networks to enable network access ubiquity. Unfortunately, this integration of different networks results in performance degradation when handovers occur among the networks during a mobility event. Thus, there is a requirement for effective mobility management protocols to support ubiquitous network access by providing seamless handover. This paper examines the handover performance of Proxy Mobile IPv6 mobility management protocol when used with and without the IEEE 802.21 Media Independent Handover services in a heterogeneous wireless networks' environment.
