2.1 Introduction
e simplicity in deployment makes mobile ad hoc networks (which
do not require any infrastructure) suitable for a variety of applica-
tions, such as collaborative computing, disaster recovery, and battle
field communication. With the proliferation of communications and
computing devices, such as mobile phones, laptops, or PDAs, per-
sonal area networking (PAN), which is an ad hoc networking-based
technology, has recently gained much interest.
In ad hoc networks, transmitters use radio signals for communi-
cation. Generally, each node can only be a transmitter (TRX) or a
receiver (RX), one at a time. Communication among mobile nodes
is limited within a certain transmission range. And nodes share the
same f
