“…We observed that, reducing the guard band size any further affected the synchronization. To enable the TDMA-based MAC protocol as suggested by [1], we have used the algorithm in [8] as the slot scheduling algorithm. After experimenting with the number of neighbour nodes, we arrived on a maximum value of 50 neighbour nodes.…”

“…It is required that a TDMA slot allocation algorithm, such as RD-TDMA [8] is run before the clock synchronization protocol runs and each node knows its slot number in the TDMA frame. The slots should be unique in the 2-hop neighbourhood of each node, so as to prevent the problems posed by the hidden nodes [9].…”

“…The concept can be integrated into IEFCS and IWECS protocol as well. Initially, TDMA slots for each node for local broadcast are decided using a slot allocation protocol such as the one given in [8]. Then the clock synchronization protocol starts using CSMA-based channel access for the first few synchronization phases.…”

Clock synchronization protocols in wireless sensor networks (WSNs) provide a uniform notion of time which is required by both system as well as application level programs of WSNs. Since nodes have limited energy, it is required that the energy consumed by the clock synchronization protocols is as minimum as possible. Synchronous clock synchronization protocols execute their clock synchronization process at each node, roughly during the same real-time interval, called synchronization phase. The energy consumed by these protocols depends on the duration of the synchronization phase and how frequently the synchronization phase is executed. Hence, to minimize the energy consumption by each node, the duration of synchronization phase should be as small as possible, and the interval between consecutive synchronization phases as large as possible. Due to different drift rates of the clocks, the synchronization phases at different nodes drift apart and special techniques are required to keep them in sync. Keeping synchronization phases at neighbouring nodes in sync helps to reduce the synchronization phase. In this paper, we propose a novel technique using TDMA-based MAC protocol to keep the synchronization phases at neighbouring nodes in sync much more tightly than the existing techniques. We have applied the technique in the improved weighted-average based clock synchronization (IWICS) protocol to reduce the synchronization phase considerably and the modified TDMAbased IWICS protocol is named TIWICS protocol. This reduction in energy consumption is achieved without reducing the synchronization accuracy. Simulation results obtained using Castalia network simulator and the experimental results obtained using a testbed of WSN consisting of a few TelosB motes confirm the effectiveness of the approach.

“…TDMA scheduling is a typical method of interference management in the time domain [25], [26]. A randomized distributed TDMA scheduling (RD-TDMA) algorithm to generate a feasible schedule and handle the correlated contention quickly has been presented in [25]. In [26], the authors formulated the cooperation of SBSs as an overlapping coalition formation game (OCFG) to manage the interference, where each coalition avoided the co-tier interference by the use of TDMA scheduling.…”

Extensive deployment of heterogeneous small cells in cellular networks results in ultra-dense small cell networks (USNs). USNs have been established as one of the vital networking architectures in the 5G to expand system capacity and augment network coverage. However, intensive deployment of cells results in a complex interference problem. In this paper, we propose a distributed multi-domain interference management scheme among cooperative small cells. The proposed scheme mitigates the interference while optimizing the overall network utility. Additionally, we jointly investigate OFDMA scheduling, TDMA scheduling, interference alignment (IA), and power control. We model small cells' coordination behavior as an overlapping coalition formation game (OCFG). In this game, each base station can make an autonomous decision and participate in more than one coalition to perform IA and suppress intra-coalition interference. To achieve this goal, we propose a distributed joint interference management (JIM) algorithm. The proposed algorithm allows each small cell base station to self-organize and interact into a stable overlapping coalition structure and reduce interference gradually from multi-domain, thus achieving an optimal tradeoff between costs and benefits. Compared with existing approaches, the proposed JIM algorithm provides appreciable performance improvement in terms of total throughput, which is demonstrated by simulation results.

Heterogeneous wireless sensor network (WSN) is used in infrastructure monitoring, animal monitoring, smart building and environmental monitoring. Several research has been done to detect energy efficiency concerns, but none of them has been successful. In this proposed model, the clusters are formed using K-means clustering algorithm for the sensor nodes. MOA is used in combination with an energy efficient routing protocol to select the CH. Sub-clusters are formed because of the nodes that cannot survive with the CH. To transfer the data from CH to the base station, each and every sub-cluster selects a separate CH. When the energy level of the CH becomes low, the selection process of CH will start again and a new CH will be selected according to the fitness evaluation of the efficient routing protocol. The performance of the mobile sensor nodes is determined using the residual energy, network lifetime, number of data packets sent to the sink and number of dead nodes. The proposed model performed better than the existing techniques such as LEACH, LEACH-PSO and SEECP. Simulation results illustrate that the proposed model enhances the life time of networks, nodes' energy consumption rate and exhaustion ratio for every node by more than 4.12%, 5.76% and 6.18%.
