The Future Networks' vision towards a diverse wireless networking world, considers the support of any service, at any time delivered in a transparent optimized way. The demand for multimedia services delivered " anywhere and anyhow" has increased tremendously over the last few years leading to the evolution of the wireless industry towards all-IP networking. The research effort for the interworking heterogeneous technologies (e.g. WLANs, ad-hoc, wireless mesh, 4G, WiMAx, LTE etc.) amplifies the

The QoS of multimedia services such as IP telephony, video-on-demand and mobile video will depend greatly on the ability to minimize the impact of the handover, hence traffic redirection in a seamless and secure transparent manner. Furthermore, Cross-layer and Cross-system optimization solutions will also be the enablers to deliver multimedia services over heterogeneous networks in a cost-effective manner. The main objectives in this special issue are to address novel research results in the areas of resource and mobility management protocols and cross-layer techniques to facilitate effective cooperation among heterogeneous wireless networks thus enabling seamless service mobility to the 'end-user' in an optimized way. They study the scalability of routing schemes for ad-hoc networks using explicit clustering. They compare an advanced version of the Ad Hoc Distance Vector Algorithm (AODV) by incorporating the Metrical Routing Algorithm (MRA) that possesses the natural clustering property. The second paper entitled 'Timely Effective Handover Mechanism in Heterogeneous Wireless Networks' by Sang-Jo Yoo, David Cypher, Nada Golmie propose a new predictive handover framework in order to achieve seamless handover in diverse wireless environments. Their approach uses the neighbor network information to generate timely the link triggers
