Private and Mobile inter-network routing for Wireless Sensor Networks and Internet of Things

In the last few years, using the Internet of Things has been expanded in many areas, such as environmental monitoring, industries, and smart home. Since the Internet of Things has a direct relation to human life, its security is of paramount importance. Therefore, the communication between the nodes should be secured and the valuable private information should be kept private so that the attacker cannot detect the network structure. This article provides a protocol that can handle routing privately. To do this, we use the data structure called Spatial Bloom Filter (SBF). In addition, the proposed protocol uses random identifiers instead of IP addresses, so that an attacker cannot collect network structure information and location of nodes from IP addresses. Using a homomorphic encryption scheme, the protocol prevent attackers from retrieving valuable network information, if they can infiltrate to one or more network nodes. Also, since almost all nodes in the internet of things are mobile, the structure of networks and subnets is constantly changing. The proposed protocol has the ability to manage to route in networks with a dynamic structure

PMSS: Producer Mobility Support Scheme Optimization with RWP Mobility Model in Named Data Networking

Abstract: The movement pattern of mobile producer plays an important role in mobility performance analysis of the wireless and mobile network. However, the producer mobility behavior is directly affecting the handoff latency and signaling overhead cost. Many researchers provide analytical investigation to analyze and solve the handoff problems and compared with the simulation result. To justify between simulation and analytical investigation, movement behavior of mobile node needs to be included in the analytical investigation to make it possible to compare with the simulation-based result. This paper incorporated Random WayPoint Mobility (RWPM) model, to determine the behavior of mobile producer, for analytical solution of producer mobility support in NDN. In this paper, we introduce mobility Interest packets to conveyed new prefix or location of mobile producer, a broadcasting strategy to facilitate the handoff process and the immobile anchor router was modified to perform a dual function that is, tagging of anchors and broadcasting of tagged mobility Interest packets. The performance analysis for mobile producer behavior and handoff latency shows that our proposed Producer Mobility Support Scheme (PMSS) reduces handoff latency compared to DNS-like and Home Agent routing approach
