Abstract

Wireless mobile communication (WMC) devices located in near proximity of each other may be enabled to form a mesh (ad hoc wireless) network. WMC devices may form and/or tear down intra-mesh connection with other WMC devices in the same mesh network. WMC devices may utilize information related to other WMC devices in the mesh network in determining formation and tearing down of intra-mesh connections. This information may comprise relative speeds, locations, and directions of movement of the WMC devices forming/tearing intra-mesh connections. Other information including data bandwidth and/or power consumption may be utilized in such determination. This information may also comprise available services advertised by WMC devices in the mesh network.

Claims
