Abstract
The wireless mesh network is an emerging technology, offering innovative and efficient solutions typically used for last-mile broadband access. Multicasting is a mode of communication that delivers data from a sender to a set of receivers simultaneously in an effective way. This article deals with the problem of assigning synchronized time slots among the forwarded nodes in the multicast group of a wireless mesh network. To solve this problem, we propose a MAC layer solution that developed with snoozing and awaken slot durations for each node to pick the channel at a specific time and during the remaining period, the node will be in an idle state to listen for the packet arrival using Galois estimation. This mechanism divides the available time into slots depends on the demand of the node transmissions and channel availability. During transmission, each node comes to the awaken state and once the transmission completed the node goes to the snoozing state to preserve the energy. The slot allocation is assigned to each node based on the binary track of the span duration and transmission demands. The slot allocation based on multicast packet forwarding technique reduces the energy expense among nodes and supports to balance network communication duration. This shared slot allocation also minimizes the congestion on the network and creates healthier channel usage during communication. The Simulation results show that the proposed approach has achieved a better outcome than previous works in terms of minimum delay and high throughput.
Highlights
A wireless mesh network (WMN) is an infrastructure of nodes that are wirelessly connected to each other [1]
During multicast routing in a mesh network, time slot (TS) for the data transmissions between nodes and the snoozing (SN) forecast to inform the channel usage among the nodes are computed by using Galois estimation (GE) with the binary forecast track pattern (BT)
In turn to have an overlapped awaken slot, two nodes channel must be connected as d1 = d2, in sequence to find the time slot k0, we can discover the solutions of the dissimilarity polynomial fTS1 (k0) – fTS2 (k0) = 0, the volume of the overlap slots was precisely similar as the quantity of their diversification polynomial degree (PD)
Summary
A wireless mesh network (WMN) is an infrastructure of nodes that are wirelessly connected to each other [1]. The mesh router act as a forwarding node among the clients and the internet servers to serve the internet benefits to the clients and the gateways enable the integration of WMNs with other networks. Upon receiving the packets from the source node, the receiving router retransmits that to all the attached interfaces in the group. Require that data be sent immediately [3, 4] and communication has to be done without interruption and delay [5,6,7] This leads to developing a time slot allocation mechanism under the multicast scenario in WMN.
