1.1 Wireless Ad Hoc Networks
Wireless ad hoc networks are a category of wireless networks that utilize multi-hop relaying
of packets yet are capable of operating without any infrastructure support (Perkins 2001;
Ram Murthy and Manoj 2004; Toh 2002). Such networks are formed by a number of
devices, possibly heterogeneous, with wireless communication capabilities that connect
and disconnect at will. In addition, some or all of those devices may be mobile and are
thus able to change their location frequently; ad hoc networks with mobile nodes are
often referred to as mobile ad hoc networks, or MANETs. Even without mobility, nodes
can join and/or leave an ad hoc network at will, and such networks need to possess self-organizing
capability in terms of media access, routing, and other networking functions. Ad
hoc networking includes such diverse applications as mobile, collaborative, and distributed
computing; mobile ... read full excerpt from Wireless Personal Area Networks: Performance, Interconnection, and Security with IEEE 802.15.4 ebook
