Main peculiarities of ad hoc networks which typically require new solutions for distributed signal processing and control can be summarized as follows autonomous and spontaneous nature of nodes which leads to dynamic unpredictable topology mobility of nodes which may cause link failures and network partitions battery limitations which imply constraints on transmission power and network connectivity need of cooperative and or opportunistic behaviour in spite of the natural energy-conservative selfish attitude of nodes. The traditional layered protocol architectures are not well suited to deal with the above-multifaceted issues because they do not exploit the potential improvement in performance that can be obtained through cross-layer design. Typical examples of transversal objectives which deserve joint interaction of algorithms and techniques that span multiple layers are energy efficiency quality-of-service support reliability network scalability. This special issue has been conceptualized within the framework of the IST-FP6 Network of Excellence in Wireless Communications NEWCOM and more specifically within the context of the NEWCOM Project A on Ad Hoc and Sensor Networks. It contains thirteen papers which are all communed by their focus
