“…Enhancing data load traffic balancing across sensor nodes also enhances energy efficiency, which prolongs the nodes and network lifetime. The link capacity is limited due to the utilisation of a shared channel within a single-path scheme such that the use of other alternative paths increases the interference and data collision [74,75] leading to limiting the design of efficient multi-path routing protocols. To solve such a problem, various techniques including location-aware routing [76,77], multi-channel data transmission [18][19][20][21] and directed antenna [17] are incorporated to reduce the channel interference.…”

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

Multipath routing is one of challenging issues for improving the reliability of end-to-end data delivery in wireless sensor networks. Recently, a disjointedness and management of path have been studying to enhance the robustness and efficiency of the multipath routing. However, previous multipath routing protocols exploit the disjointed multipath construction method that is not to consider the wireless communication environment. In addition, if a path failures is occurred due to the node or link failures in the irregular network environment, they maintain the multipath through the simple method that to construct a new extra path. Even some of them have no a method. In order to cope with the insufficiency of path management, a hole detouring scheme, to bypass the failures area and construct the new paths, was proposed. However, it also has the problem that requires a heavy cost and a delivery suspension to the some or all paths in the hole detouring process due to the centralized and inflexible First Author：충남대학교 컴퓨터공학과 컴퓨터네트워크 연구실,

“…Different degrees of disjointness can be considered, from non-disjoint paths to linkdisjoint, node-disjoint or even spatial disjointness. A degree of spatial disjointness is necessary in case of load balancing in MANETs due to interference between paths [9], [11], [12].…”

In this paper we propose a multipath extension to Dynamic MANET On-demand (DYMO) Routing protocol. Multipath protocols have been shown to benefit on-demand routing in MANETs, where the knowledge of alternate paths allows to reduce the frequency of route discovery in the presence of link failures. Route discovery is an operation which accounts for most of the overhead of these protocols. This is specially helpful in scenarios with node mobility where link failures are frequent. Our extension is based on AOMDV. It can discover multiple disjoint paths in one route discovery with minimal additional overhead over DYMO. We analyze the performance gains of using alternate path information with DYMO. Simulation results show that multipath routing greatly benefits DYMO in reducing overhead and therefore increasing performance.
