Abstract: In a mesh communication network, a poll request protocol (PRP) is provided in which a special packet is broadcast by the congested node (12) when it is ready to provide services. The controlling node (14) (usually the more congested node) broadcasts a packet to request poll signals from nodes desiring resources of the controlling node(14). The contending nodes (12) then have equal chances to request the services of the controlling node (14) by sending poll signals. The controlling node (14) can then arbitrate the requests, determine the most fair and efficient use of its resources, and broadcast a scheduling packet to inform the contending nodes (12) then send their packets to the controlling node (14) without loss packets caused by congestion collisions. The controlling node (14) can then send data to the contending nodes (12) also without lost packets.

Abstract: In a wireless communication system (10) having sometimes mobile subscriber units (124, 125) and a plurality of fixed network devices (100, 101, 102, 103) located at cell sites, a multimode acquisition protocol is provided at each subscriber unit (124, 125) which first senses whether the subscriber unit is static or mobile from the nature and quality of the communication links with nearby network devices (100, 101, 102, 103) and then enables an acquisition protocol suited to either static mode or mobile mode. In a specific embodiment, the protocol initiates procedures to change acquisition mode from static to mobile upon failure of the subscriber unit to sense three consecutive scheduled polling packets sent by a linked network device or upon loss of communication with any locally-known network device or upon failure to transmit 25 consecutive data packets. In such case, the procedure is initiated to determine whether it is appropriate to switch to a mobile mode for purposes of acquisition.
