Currently, Cyber Physical Systems (CPS) and/or IoT play predominant roles in the cloud communication domain. The main aspects of these types of systems are Wireless Sensor Networks, Cloud and Communication Networks. The data which needs to be disseminated from multiple sources to the destination base station, or sink, is of vital significance. There are many problems which can occur when data is conveyed to the sink. The sink is connected to the cloud via a communication network. The congestion, reliability, delay, fairness, etc. are all of main concern. These can be treated as Quality of Service parameters that govern the performance of the CPS. Above all, energy consumption is the main constrain for WSN node. It is extremely difficult to obtain good QoS by keeping energy consumption low. Even the response of one of QoS parameter depends on the many other QoS parameters. Care must be taken on all QoS parameters in order to improve the performance of the wireless sensor networks. This Quality of Services may improve the application base of the CPS. With the QoS parameters the data dissemination along with energy optimization is affected. The performance of the WSN needs to be regularly checked against the QoS metrics for different data inputs. This may contain the periodic- or non-periodic data, event based data, transient or busty data. Topics discussed in book: Emphasis is given on QoS parameters and their improvement in Network Delay, Throughput, Packet Delivery Ratio (PDR), Packet Loss Ratio (PLR), Energy Consumption, Congestion Control, Reliability, Fairness, Delay, Jitter

Most existing research in wireless sensor networks (WSNs) has been focused on proposing protocols to facilitate either energy effient communication or sensing operation in WSNs. We believe that there exist fundamental limits in the operations and the parameters of WSNs. Characterizing these fundamental limits, establishing the relationships between the parameters and the WSN performance, and identifying the tradeoffs among different performance measures can provide us insights in designing sensor networks. In this dissertation, the QoS properties of WSNs, including the coverage, reachability, and delay, are analyzed in an analytical framework. How the network parameters, such as the node density, sensing range, transmission range, impact the aforementioned QoS properties are investigated by abstracting the randomly deployed WSNs as random geometric graphs. Both homogenous and heterogenous sensor networks are addressed. Based on the analytical model, optimal sensor network parameters can be chosen to improve the network performance while achieving pre-specified QoS constraints. Besides this abstraction, practical issues affecting the QoS performance of WSNs are also examined by doing extensive simulations in this dissertation. Specifically, results are obtained for the QoS properties in the flooding of WSN when a cross-layer approach is adopted, and other practical issues such as channel fading and MAC layer contention are taken into account. The results show that exchanging more information across the layers can help improve effciency of the protocol. It is further shown that wireless fading helps to reduce the hop count, although it makes the transmission range less predictable and limits the improvement in the performance of such cross-layer design in WSNs.

In this Book we start from basic algorithms and some popular cluster-based routing schemes towards achieving the required goal of energy-efficiency to prolong network lifetime, then we propose a modification on EEPSC to achieve the desired goal of prolonged network lifetime- distributing the load evenly among the nodes. This is achieved by placing the cluster-head at a location as central as possible in a cluster so that the energy-consumption in intra-cluster communication (member node to cluster-head) could be minimized.You will enjoy implementing and see things working, source code are available with author on demand.Happy Learning!!
