ABSTRACT:
A wireless network is disclosed that comprises base transmitter/receiver stations coupled to a trunk communications network and several mobile computing devices that are capable of transmitting and receiving messages. Messages to be transmitted will be encrypted and digitally signed to insure privacy and authentication of the messages. Each mobile computing device that participates in the wireless network is capable of voluntarily allocating some amount of memory for cooperative messaging storage. Each mobile computing device is responsible for receiving messages addressed to other devices, storing the received messages in the allocated memory and then periodically retransmitting the received messages. Each message includes a unique serial number and time/date stamp. The message serial numbers are used to prevent duplicate messages being stored in the allocated memory. Furthermore, the time/date stamps on the messages stored in the allocated memory are periodically examined such that outdated messages are automatically killed after some specified time interval.
