The IEEE 802.15 Task group 5 is chartered to determine the necessary mechanisms that must be present in the PHY and MAC layers of WPANs to enable mesh networking.

A mesh network is a PAN that employs one of two connection arrangements, full mesh topology or partial mesh topology. In the full mesh topology, each node is connected directly to each of the others. In the partial mesh topology, some nodes are connected to all the others, but some of the nodes are connected only to those other nodes with which they exchange the most data.

Mesh networks have the capability to provide:

1.      Extension of network coverage without increasing transmit power or receive sensitivity

      2.      Enhanced reliability via route redundancy

3.      Easier network configuration

4.      Better device battery life due to fewer retransmissions
