“…The MAC layer defines the data link between two mesh nodes and exchanges MAC Service Data Units (MSDUs) packed into MAC Protocol Data Units (MPDU) and carried over the PHY Protocol Data Unit (PPDU) as per the original 802.11 MAC standards. The main concern observed in a wireless mesh is that the standard requires every successfully non multicast and broadcast frames received at each mesh node to be acknowledged causing considerable packet delays in multi-hop communications (a frame needs to cross multiple hops in reaching the destination) [6] [7].…”

“…The scenario called spatial bias where more the mesh hops in a mesh path, higher the frames affected which is scalability concern in designing WMN. Research has shown that the bandwidth starvation due to spatial bias in multi-hop could be optimized by dynamically adjusting the packet size and the minimum contention period based on congestion experienced due to spatial bias [6]. Figure 7 shows the access control mechanism based on arbitration inter-frame space (AIFS) in EDCA.…”

Abstract:The wireless mesh networks have been a very promising solution for providing last few miles wireless connectivity in the metropolitan area networks. A new medium access control scheme is proposed to improve throughput in wireless mesh networks. The proposed scheme is to adjust the minimum size of contention window of mesh clients according to the information of transmission queue at relay nodes. The relay node carries the load information on an ACK frame by using the reserved subtype fields. The proposed scheme gives a priority to the relay node for transmitting packets when the relay node becomes a bottleneck. The simulation results show much better performance from the proposed scheme in comparison with that from original CSMA/CA scheme.

Wireless sensor networks for forest monitoring are typically deployed in fields in which manual intervention cannot be easily accessed. An interesting approach to extending the lifetime of sensor nodes is the use of energy harvested from the environment. Design constraints are application-dependent and based on the monitored environment in which the energy harvesting takes place. To reduce energy consumption, we designed a power management scheme that combines dynamic duty cycle scheduling at the network layer to plan node duty time. The dynamic duty cycle scheduling is realized based on a tier structure in which the network is concentrically organized around the sink node. In addition, the multi-paths preserved in the tier structure can be used to deliver residual packets when a path failure occurs. Experimental results show that the proposed method has a better performance.
