COMMUNICATION METHOD AND SYSTEM USING RR-ALOHA BASED PROTOCOLS

摘要

A communication method and system in an Ad-Hoc network using a RR-ALOHA based protocol are provided. The method may include: receiving a data frame which includes N slots, where N is a positive integer greater than two, where a slot includes a payload and a frame information field, where a frame information field includes N sub-frame information fields which correspond to the N slots, respectively, where a sub-frame information field includes a source temporary identifier field for indicating which node occupies its corresponding slot; and if a source temporary identifier field contained in the received data frame equals to a first predetermined value representing the status of free, determining that a corresponding slot is free and can be reserved. By using the method of the disclosure, communication efficiency is improved.

主权项

1. A method for determining whether a slot is free in an Ad-Hoc network using an RR-ALOHA based protocol, comprising:
receiving a data frame that comprises N slots, where N is a positive integer greater than two, where each slot comprises a payload and a frame information field, where each frame information field comprises N sub-frame information fields that correspond to the N slots, respectively, and where each sub-frame information field comprises a source temporary identifier field for indicating which node occupies the slot corresponding to the source temporary identifier; and determining that a slot corresponding to a first source temporary identifier is free and can be reserved, if the first source temporary identifier field contained in the received data frame equals to a first predetermined value representing a status of free.
