INTRODUCTION

The use of WSNs for mission critical applications have brought to light concerns regarding QoS provisioning since the mentioned applications require performance guarantees from systems in which they are implemented. The rapid growth in the number of users and applications using WSNs has led to WSNs becoming increasingly complex. Hence, this growth has triggered high demands on WSNs to provide QoS requirements for every user and application that uses them, as a means to enhance their operation. Even though WSN technologies have limitations, they possess the potential to support modern high demand network computing applications if they could be optimized accordingly. However, it is yet to be realized as to how WSN systems could support QoS provisioning in modern network application systems, since these technologies suffer in terms of computing capabilities. Hence, this work, makes reference to the need for efficient resource management to realize the required QoS in WSNs.

PROBLEM STATEMENT

This subsection provides a detailed description of experienced challenges within the proposed area of research, especially for mission-critical application systems. These experienced challenges are described in the context of how QoS can improve WSN network operations using software-oriented strategies. Furthermore, the criticality of implementing QoS requirements to modern network computing systems is provided with the aim to support the systematic opportunity that can be achieved from the proposed research approach.

RESEARCH OBJECTIVE AND QUESTIONS

This subsection provides a list of questions that came about when conducting this study, with the objectives that have been developed to address these questions as well as provide a direction towards the implantation of the proposed approach.

OBJECTIVES
