Title: NETWORK PROTOCOL FOR WIRELESS DEVICES UTILIZING LOCATION INFORMATION
Abstract:
A system and method for establishing a network within a plurality of interconnected and randomly geographically located nodes, such as wireless devices. One or more cluster heads (30) are selected within the nodes and selectively communicate with the other cluster heads (30) and nodes. The cluster head (30) can be a wireless device or a specific dedicated device such as a router. Each cluster head (30) determines the geographical location of that cluster head (30) and the data-dependent nodes of the cluster head (30), and selectively receives and stores location information of the other cluster heads (30) and dependent nodes to create an optimal data-routing network within the plurality of nodes.
