Wireless Sensor Networks (WSNs) are widely used in various real time applications such as surveillance, environment monitoring, studying wildlife habitat and so on. As the nodes in the network are resource constrained, they are vulnerable to various attacks. This is the reason there is need for secure data collection in such networks. Many solutions came into existence to provide secure communications in WSN. However, the solutions were based on different techniques. Minimization of packet failure rate is one of the objectives of many researchers in this area. The potential attacks on the network can jeopardise its purpose. Recently Alghamdi et al. proposed a solution using multipath routing in which the effect of adversaries is reduced besides ensuring secure data transmission in the presence of malicious nodes in the network. Our work is similar to this with certain improvements in terms of energy consumption and also packet delivery failure ratio. We implemented a WSN with simulations and our approach used a controller in the network which, in consultation with base station, can play a vital role in prevention of attacks. Since the solution is based on randomized multipath routing, it is able to withstand potential attacks and ensure that the failure of packet delivery is minimized and the overall network performance is improved. The simulation results reveal that the proposed approach has better performance in terms of performance level of protocol, network throughput, delay analysis, percentage of packet loss, and energy consumption.
