Priority and interference aware multipath routing based communications for extreme surveillance systems

Increased natural disaster in various urban and rural areas requires immediate attention to avoid the major causes. In real world, immediate recovery to the disaster areas is ensured by adapting the unmanned aerial vehicles that enable people to reach the disaster areas immediately. Here specific task in the disaster area can be completed efficiently by working with multi Unmanned Aerial Vehicle (UAV) instead of single UAV. Here data communication between the UAV needs to be very reliable to ensure the proper disaster management outcome. It is more complex to provide the required services to the users when there is situation arise to switch between the heterogeneous networks. The QoS-Oriented Distributed routing protocol (QOD) is used in the existing methods to give solution to this problem. The data is transferred between hybrid networks with required QoS. In the existing work, routing is done by considering the QoS consideration thus the efficient and reliable distributed routing is guaranteed. However the existing work lacks from the following issues: It avoids the data transfer through the path in which data transmission is going already to avoid the interference problems which might reduce the throughput rate. Priority of the data transferred from multiple sources are not considered in the previous work and also existing work focused on reducing delay alone as QoS factor. Priority and Interference aware Multipath Routing Protocol (PIMRP) is introduced to rectify this issue in the proposed method. In this method, interference aware and priority routing is ensured by introducing the following research methods. Here, Multipath interference based routing method is used allow transmission of data from multiple path that resides within interference range with guaranteed interference avoidance and increased throughput. Here route path nodes are selected with multiple objectives such as delay, bandwidth, and energy consumption. To provide more preference to the prioritized data transmission nodes with more resource availability is provided to the prioritized data packets which are tiny segmented. The performance of the proposed method is evaluated using NS2 simulation tool. The simulation results confirm the efficiency of the proposed method.
