| 1. A communication protocol for a personal area network, said protocol comprising the steps of:
receiving a frame at a node;
selecting a routing protocol based on content of said frame and on resources of said node, wherein selecting said routing
protocol further comprises the steps of:
evaluating a destination address of the frame to determine whether said frame is to be broadcast;
when said destination address is a broadcast address, broadcasting said frame;
when said destination address is a non-broadcast address, determining whether a routing table entry exists for the destination
address;
when a routing table entry exists for the destination address, determining a route for said frame based on a table-based routing
protocol; and
when a routing table entry does not exist for the destination of said frame, evaluating a route discovery flag in said content
of said frame and evaluating the resources of said node to determine a route for said frame; and
routing said frame according to the selected routing protocol.
