Wireless sensor networks become more and more attractive for a broad variety of application scenarios. Wireless Sensor Network (WSN)s are cheap and can be easily deployed as well as that they require by design low maintenance effort. But running installations are still rare, because real world requirements and environmental conditions are even today a big challenge. Especially in multi-hop networks...
Cognitive Radio Networks have been proposed to solve the problem of overcrowded unlicensed spectrum by using the cognitive ability built in software radios to utilise the underutilised licensed channel when the licensed users are not using it. Successful results from the research community have led to its application to wireless technologies like Ad Hoc networks due to their extensive advantages....
Mobile Ad hoc Networks (MANETs) are a type of wireless network that has no fixed infrastructure and wireless nodes move arbitrarily. The MANETs are helpful in situations such as emergency search and rescue operations, battlefields, exhibitions, and conferences. Limited battery and low bandwidth are some of the main constraints in a wireless network. Moreover, nodes mobility causes network topology...
