IEEE 802.11b is wireless local area network communications standards
that operate in the 2.4GHz band at data rates of 2 to 11Mbps and distances
of 25 to 300 metres [2]. In an IEEE 802.11 network,
there are two possible modes: ad hoc mode, where all nodes in the
network must be within range of each other, and the infrastructure
mode, in which all inter-node communication must pass via access points.
The ad hoc mode allows for ad hoc network of nodes, but communication
is point-to-point, with no multihop capabilities. Since the IEEE 802.11
standard only defines the physical and data-link layer, it is up to
upper layer protocols to incorporate multihop capabilities. Unlike
Bluetooth, IEEE 802.11b products are widely available.
