“…In [11] authors discussed that superior transmission, reception, and interference suppression capabilities of smart antennas have inspired the consideration of their use in wireless ad hoc and mesh networks that are inherently interference limited. However, the capabilities of the antennas can be effectively leveraged only through appropriate changes to higher layer network protocols [12]. Hence, in recent years, several researchers have investigated the changes need to be made at the MAC and upper layer to leverage the unique capabilities of smart antenna technologies.…”

Wireless Mesh Networks (WMNs) consist of mesh clients and mesh routers, where laptops, cell phones and sensor nodes are mesh clients, while mesh routers with minimal mobility are used for data forwarding. In this paper we focus on the improvement of wireless mesh network performance using smart antenna, and in particular, switched beam directional antennas. We have used STDMA(Spatial Time Division Multiple Access) medium access control (MAC) protocol, where links are preassigned time-slots according to a schedule in such way that interference is avoided allowing dense reuse of time slots within the network. An antenna uses different patterns depending on the direction towards a communication need to be established. Switching from one radiation pattern to other radiation pattern consume energy and take some time to stabilize new radiation pattern. We have analyzed the methods that are used to schedule the time-slots and minimize the number of switchings for communication.

“…The deafness issue is related with the Request To Send (RTS) or Clear-To-Send (CTS) packet in the IEEE 802.11 MAC protocol [72] and happens when a transmitter sends a control packet to start a transmission while the goal is tuned to another channel. In the wake of sending different solicitations, if the transmitter does not get any reaction, it might show that the receiver is unreachable [11], [73]. Fig.…”

Perceptions of lifelike marvels are viewed as the best data source of unconstrained synchronization. Such synchronization is imperative for the best possible coordination of intensity cycles for wireless sensor network (WSN) energy conservation. Fireflies, which have a comparative structure to WSN, utilize the guideline of pulse-Coupled Oscillators (PCOs) for light blaze outflow to pull in mating accomplices. This conduct can be impersonated for the improvement of WSNs and have decentralized energy efficiency conduct. In any case, a fascinating component of WSNs is that the PCO is utilized by the firefly synchronization to pull in mating accomplices; however, it cannot be utilized in genuine sensor networks. This is because of the failure of the sensor nodes to get data packets utilized by the first PCO model because of deafness. Subsequently, energy utilization turns out to be high and a large portion of the data is lost. For most situations, the PCO model is not appropriate for sensor networks because of high packet collision since WSNs cannot bear the cost of transmission and gathering data concurrently. It likewise expands energy utilization because the battery substitution is unthinkable upon the fatigue of a node battery energy strategy. Accordingly, this paper broadly surveys and talks about the algorithms developed to address the difficulties and the systems of incorporating energy-efficient firefly inspired time synchronization over WSNs and the properties of transmission state inside the deafness and packet collision. In particular, it is an exhaustive audit incorporating instrument, points of interest and detriments of past related work inside the transmission state. The paper helps scientists to (1) keep away from deafness that happens in the transmit state in WSNs, (2) prevent packet collision for the time of transmission in WSNs, and (3) increment the data gathering all through the transmission states in WSNs. It additionally features the recommendation of a few appropriate open issues as proposals for future research.

The last few years have experienced a high growth rate in research area of wireless mesh networks (WMNs). The attractive characteristics of WMN are self-organize and selfconfigure, low set-up/installation costs, simpler maintenance tasks, and service coverage with high reliability and faulttolerance. WMN also provides their integration with existing wireless networks such as cellular networks, WLANs, wirelessfidelity (Wi-Fi), and worldwide interop-erability of microwave access (WiMAX). WMNs application areas are broadband home networking, community networking and commercial /business networking. We have focused the performance improvement of WMN using the directional antenna in this paper. Spatial Time Division Multiple Access (STDMA) a variant of access method has been used in which same slots can be reused that are sufficiently far apart to avoid the interference but it required scheduling algorithms. Directional antenna uses the different radiation pattern at different instant of time according the direction of communication. Switching from one radiation pattern to other is required when route of communication is changed. Switching from one radiation pattern to other pattern consume energy and take some time to stabilized new radiation pattern. We have analyzed the methods, used for scheduling the time slot and minimize the number of switches for communication.
