Hybrid Wireless Mesh Protocol takes advantages of both reactive protocol AODV and proactive protocol OLSR.This protocol has been proposed by 802.11s task group as a default and the standard is expected to be published by 2010 (Bahr, 2008).
Communications company Motorola Inc (NYSE:MOT) has confirmed that its MeshConnex networking technology will support the final 802.11s meshing standard being developed by the IEEE (Institute of Electrical and Electronics Engineers Inc).
Section 2 provides some useful knowledge about MAC layer; Section 3 gives an overview of media access standard of IEEE 802.11s. To provide an effective way forward in multi-radio multi-channel mesh channel assignment, section 4 reviews heuristic based channel assignment proposals by categorizing varying environments, e.g.
The IEEE 802.11s standard  provides a security mechanism known as Simultaneous Authentication of Equals (SAE), which uses finite field cryptography, using which the nodes authenticate each other with a password.
