Abstract: In order to improve the performance of 3D wireless sensor networks, an Iterative Split Clustering Energy Angle Routing (ISC-EAR) Algorithm is proposed. The design idea is discussed theoretically, and the design idea is as follows: on the basis of the link bandwidth and other meeting user QoS requirements, all nodes within the node perception radius or communication radius are regarded as next hop candidates. Select the next hop node according to the total energy consumption of the node (including sending and receiving energy consumption), and try to ensure that the farthest transmission distance consumes the least energy. Select the current node, the destination node and the next hop node, the space vector with the current node as the vertex has the smallest angle, that is, the candidate node closest to the destination node as the next hop node. In order to verify the performance of the algorithm, use C/C++ for programming simulation. Through three different topological structures of mine topology, average topology and random topology, the performance evaluation is carried out using four indicators: the number of alive nodes, network lifetime, network energy consumption and average energy of node. Through simulation calculation, the ISC-EAR routing algorithm has good technical performance advantages compared with the benchmark routing algorithm IGreedy, which can increase the survival time of nodes, reduce network energy consumption, and prolong the survival time of the network. It has better advancement.

Abstract: This paper presents a comprehensive investigation, backed up by detailed simulations, that the default settings of the software based open source Intrusion Detection and Prevention Systems (IDPs) are not enough to thwart the network attacks in a modern high-speed IPv6-only environment. It aims to solve this problem by improving the processing capabilities of an IDPS in more than one way, with each method being totally independent from the other. The proposed solution can be implemented by any user running an IDPS, without needing escalated privileges. Using and IPv6 packet generator, it is shown that with the increase in IPv6 traffic in a fixed amount of time, the IDPS fails to analyse all the packets and starts dropping them. This phenomenon compromises the core functionality of IDPS which is to stop the unwanted traffic. A hybrid solution has been proposed to increase the performance of the IDPS. Our research involves only the system running an IDPS, with little to no tweaking of the other elements within a network like routers, switches and firewalls. The paper also talks briefly about the current and the future generation of the IDPSs. The simulation with the hybrid solution concludes that the performance is improved to a staggering 200%, approximately, compared to the built-in settings of the IDPS.
