ABSTRACT:
The wireless mesh networks (WMN) have attracted much attention in recent years due to its advantages through the use of traditional wireless networks with or without mobility. A WMN can be seen as a mixture of ad hoc networks and infrastructure, with all the benefits of this hybrid architecture. A network of this type maintains the signal level over long distances through a series of shorter hops through intermediate nodes. These intermediate nodes not only regenerate the signal but also act cooperatively and smartly to extend network coverage and improve performance. This paper presents the main aspects of the design and operation of a new protocol or connection procedure that allows the extension of coverage in this type of networks for the transmission of data messages. The protocol includes messages recognition or acknowledgment of the information in the destination node and additionally provides a power saving mechanism so that the intermediate mobile nodes that operate primarily as gateways forwarding data to or from the neighboring nodes, do not run out batteries.
