However, as in their current solutions for medium access control (MAC) sub-layer protocols, channel efficiency has a margin for improvement, in this study, the authors evaluate the IEEE 802.15.4 MAC sub-layer performance by proposing to use the request-/clear-to-send (RTS/CTS) combined with frame concatenation and block acknowledgement (BACK) mechanism to optimise the channel use. The proposed solutions are studied in a distributed scenario with single-destination and single-rate frame aggregation. The throughput and delay performance is mathematically derived under channel environments without/with transmission errors for both the chirp spread spectrum and direct sequence spread spectrum physical layers for the 2.4 GHz Industrial, Scientific and Medical band. Simulation results successfully verify the authors’ proposed analytical model. For more than seven TX (aggregated frames) all the MAC sub-layer protocols employing RTS/CTS with frame concatenation (including sensor BACK MAC) allow for optimising channel use in WSNs, corresponding to 18–74% improvement in the maximum average throughput and minimum average delay, together with 3.3–14.1% decrease in energy consumption.</p>\u0000 </div>","PeriodicalId":51726,"journal":{"name":"IET Wireless Sensor Systems","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2020-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/iet-wss.2019.0003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87395829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors consider wireless sensors with a limited energy capacity that needs the energy to complete the transmission service. To extend the lifetime of the wireless sensor, it is assumed that the renewable energy resource, e.g. solar energy, is collected via the energy harvesting method. In order to provide a better bit error rate or data rate, the energy requirement of a packet may be more than one unit of energy. Furthermore, a packet may leave without finishing the service due to impatience if the patient interval is exceeded. They focus on one wireless sensor with one server and two finite queues: one packet queue and one energy queue. In the authors’ system, there are two classes of impatient customers, and each customer has to consume one or two units of energy to finish the service. First, they derive the analytical model for the considered system and find the steady-state probability distribution and performance measures of interest. Next, the impacts of different system parameters on the performance measures are studied.

In these methods, the anchor node diagonally traversed the network area and transmit broadcast packets of its position. In Diagonal-Centroid method, nodes estimated their location by the average of the received position while, in the second method, the best tree positions were selected by a heuristic algorithm to estimate the position of the nodes. In this study, the authors extend their analysis to three different scenarios including the networks with and without obstacles to investigate the effect of the obstacles in network localisation, as well as the network with different node deployments to check out the localisation coverage area and network performance. All scenarios were implemented in OMNeT++ simulator, and based on the results, the Diagonal-Centroid technique had the best accuracy, whereas Diagonal-PSO had better performance regarding the accuracy and energy consumption compared to those reported in the other related studies.</p>\u0000 </div>","PeriodicalId":51726,"journal":{"name":"IET Wireless Sensor Systems","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/iet-wss.2020.0052","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86188146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data overhead is the complication encountered while implementation trust-based method which leads to complications like congestion into the system. And also directly affects the data aggregation process, as a cumulative effect, the overall lifetime of the network is drastically brought down.

Then the values are computed by optimal trust inference model using the conditional tug of war optimisation algorithm. The data aggregation help in reducing the instantaneous data flow of the individual node to multi-hop and filters out the necessary data alone, then transmits the accumulated information to the receiving end. The energy efficiency of this proposed work is achieved through bypassing the repeated and fault data from the gathered information and in turn, it will maximise the WSN lifetime by saving its battery.

To keep this momentum, those industrial WSN (IWSN) must assure robustness, scalability, low power, and low maintenance, and the network protocol stack is an important piece of this puzzle. One great dilemma faced by IWSN protocols is how to sustain reliable radio links while avoiding draining too much energy from the battery. In this context, <i>Wireless</i> HART (WH) and ISA SP100.11a, for example require the hardware of the nodes to provide multiple power levels for transmission.
