For the phantom routing algorithm, phantom source nodes are concentrated near the real source node, and for the angle based phantom routing algorithm, phantom source nodes focus on some areas, and the existing source location privacy protection algorithm has low security cycle, a source location privacy protection algorithm of wireless sensor networks based on angle and network partition is proposed. The algorithm selects the next hop node on forwarding path according to the angle relationship between neighbors, and ensures that phantom source nodes are far away from the real source node and have the diversity of geographic location through network partition. Simulation results show that, compared with the existing source location privacy protection algorithm, this algorithm can induce attackers to deviate from the real path, and increase security cycle.

Named Data Networking (NDN) is a future Internet architecture, NDN forwarding strategy is a hot research topic in MANET. At present, there are two categories of forwarding strategies in NDN. One is the blind forwarding(BF), the other is the aware forwarding(AF). Data packet return by the way that one came forwarding strategy(DRF) as one of the BF strategy may fail for the interruptions of the path that are caused by the mobility of nodes. Consumer need to wait until the interest packet times out to request the data packet again. To solve the insufficient of DRF, in this paper a Forwarding Strategy, called FN based on Neighbor-aware is proposed for NDN MANET. The node maintains the neighbor information and the request information of neighbor nodes. In the phase of data packet response, in order to improve request satisfaction rate, node specifies the next hop node; Meanwhile, in order to reduce packet loss rate, node assists the last hop node to forward packet to the specific node. The simulation results show that compared with DRF and greedy forwarding(GF) strategy, FN can improve request satisfaction rate when node density is high.
