Wireless Sensor Networks (WSNs) comprising of battery-powered sensor nodes are being used in a wide range of applications. The feasibility of such applications is highly influenced by the longevity of these networks. In this work, we present a realistic WSN lifetime optimization framework where transmission power levels for both data and ACK packets are optimally selected (i.e., a complete link-layer handshaking cycle is modeled). Log-normal shadowing path loss model is employed to take into account the effects of path losses. We utilized the developed Mixed Integer Programming (MIP) based optimization framework to investigate the impact of data packet length on WSN lifetime. To quantify the effects of data packet length on network lifetime we explored the parameter space consisting of the number of nodes and node deployment density. Our results show that the optimal data packet length is the maximum allowed length.

“…The amount of traffic generated at node-k that flows from node-i to node-j is represented as an integer variable f k ij . We adopt Mica2 motes' energy dissipation characteristics in our model [9]. Transmission power levels, transmission ranges, and energy dissipation amounts are presented in Table I.…”

In this study, we present a novel family of mixed integer programming (MIP) models to analyze the effects of limiting hop count on Wireless Sensor Network (WSN) lifetime. We performed analysis to uncover the trade-off between minimizing the number of hops and maximizing the network lifetime by exploring the parameter space through numerical evaluations of the optimization models. Our results reveal that minimum hop routing leads to significant decrease in network lifetime (up to 40%) when compared to the maximum network lifetime obtained without any restrictions on hop count. However, the decrease in network lifetime is negligible if the minimum hop routing criterion is modestly relaxed (e.g., 3% decrease in network lifetime is possible if the minimum hop count is increased by 15%).Index Terms-wireless sensor networks, hop count, mixed integer programming, energy efficiency.

“…It was concluded that no considerable energy savings were achievable by using TPC for S-MAC; however, a maximum energy saving of 20 percent could be achieved when using the TDMA-based L-MAC. Vales-Alonso et al [26] also stated that these results cannot be applied to every MAC protocol, and thus further simulations must be performed to investigate other MAC protocols to validate the results. According to Gurses et al [25], it is possible to enhance network and link capacities by combining TPC algorithms with CSMA in wireless multi-hop networks.…”

“…The question of how much of the total energy utilised in a network can be saved by an 'ideal TPC' protocol was addressed by Vales-Alonso et al [26]. A theoretical model was developed by defining L as the ratio for energy utilised in a network with TPC to that without TPC.…”

In the recent years, we observed a rapid growing of Wireless Sensor Networks (WSNs) for research and commercial uses. Low-cost/low-power WSNs are utilised in various applications such as smart-home, industrial control, health care, agricultural fields, environmental purposes, biomedical systems, and scientific applications. The aim of this thesis is to develop a novel transmit power control protocol for multi-path non-uniform density single-channel WSNs. The developed protocol has two main purposes: (1) to reduce energy depletion and prolong the battery lifetime of sensor nodes by using transmit power control and, (2) to keep throughput and packet loss neutral by using multi-path routing. A limitation of most previous studies that minimise transmit power is that they fail to take into consideration the throughput reduction. Through a number of case studies, it was determined that trying to reduce the power by using multi-hopping also results in the reduction of end-to-end throughput. Hence, we propose using a multi-path routing protocol to maintain throughput. In this work, given our assumptions, we determined that the optimal number of hops must be between two and eight hops to save energy and the optimal number of paths is two paths to maintain throughput when the transmission rate is high. This is mainly due to the overhead of each packet as we as the receive power of the sensor nodes. It was also determined that there is no need to have more than 2 paths between source and destination in order to achieve throughout neutrality. QualNet 5.1 platform was used to develop "TPC for High Density WSNs" protocol that combines both TPC and some features of the MultiPath Optimised Link State Routing (MP-OLSR) protocols. The simulation results showed that using two, three, four and five hops scenarios can noticeably enhance the energy efficiency, and the optimal number of non-interfered paths must be two paths to enhance throughput neutrality and reduce overhead messages of IEEE 802.11g sensor nodes in a dense network.ii ACKNOWLEDGEMENTS
