Ad Hoc Networks

Ad hoc networks do not require base stations nor wired fixed networks. It is a distributed-controlled autonomous network composed of mobile terminals. Development of ad hoc networks is expected as an information infrastructure in twenty-first century. Packet radio and wireless circuit connection technologies can be used for realizing wireless multihop communication, which is a basic feature for ad hoc networks. There are a number of technologies and issues in areas such as routing and multicast for efficient communication and information sharing using wireless multi-hopping. Applications on ad hoc networks include information sharing at conference sites, sensor networks, and realization of convenient and comfortable local communities
