Abstract

Wireless communication devices today require connection to a relay infrastructure and the charging of expensive carrier fees for its use. The alternative for a large group of users that wish to communicate at low cost is operation within a WiFi hotspot in which devices connect through a central access point. However, such a hotspot has a limited range, must be installed in a fixed physical location, is an expense in itself, and requires administration. Users must still be within range of a hotspot and cannot communicate within any arbitrary area.

Wireless communication devices today require connection to a relay infrastructure and the charging of expensive carrier fees for its use. The alternative for a large group of users that wish to communicate at low cost is operation within a WiFi hotspot in which devices connect through a central access point. However, such a hotspot has a limited range, must be installed in a fixed physical location, is an expense in itself, and requires administration. Users must still be within range of a hotspot and cannot communicate within any arbitrary area.

The invention is for an optimized wireless peer-to-peer mesh network (such as based on 802.11 technology) that automatically populates a local map of nodes, captures presence information (and other functional parameters as described), and optimizes the routing of voice calls through nodes in a co-operative fashion based on battery power and signal strength remaining. In any local calling environment where a hotspot may not be available, each wireless device acts as an independent access point represented as a peer node, permitting point-to-point connections in peer-to-peer fashion. Namely, a device automatically finds all devices within range, and populates a list of contacts without requiring a central access point or server. To extend the available range, a mesh network is created out of all devices in the area. Devices with high battery power remaining will be used as intermediate nodes in forwarding packets in co-operative fashion between the parties engaged in a call. Encryption ensures that the data is kept private. Through a dynamically con...
