“…This has resulted in the development of various approaches for saving the limited energy of the sensor nodes, thereby extending the life of the network [6], [7], [8], [9]. Efficient algorithms can be developed at the network layer such that reliable route setup and relaying of data from the sensor nodes to the sink is achieved and the lifetime of the network is maximized [10].…”

A wireless sensor network (WSN) is a distributed network that facilitates wireless information gathering within a region of interest. The information collected by sensors is aggregated at a central node know as the sink node. Two challenges in the deployment of WSNs are limited battery power of each sensor node and sink node anonymity. The role played by the sink node raises its profile as a high value target for attack, thus its anonymity is crucial to the security of a WSN. In order to improve network security, we must implement a protocol that conceals the sink node's location while being cognizant of energy resource constraints. In this paper we develop a routing algorithm based on node clustering to improve sink node anonymity while simultaneously limiting node energy depletion. Via MATLAB simulations, we analyze the effectiveness of this algorithm in obfuscating the sink node's location in the WSN while preserving node energy. We show that the anonymity of the sink node is independent of traffic volume and that the average energy consumed by a node remains consistent across topological variations.

“…Directed diffusion is a typical data-centric protocol for WSN which laid the pivotal foundation for wireless network routing design and is leading the way in data centric protocol design. However, in this protocol interest messages are diffused to all sensor nodes by the way of flooding, which will generate a large number of redundant messages, so DD has a poor performance [3]. The clustering idea in LEACH was introduced to it, and some protocols based on clustering were proposed such as IDD DDBC.…”

Directed diffusion (DD) is typical data-centric protocol for wireless sensor networks, all nodes in a directed diffusion based network are application-aware, and this enables diffusion to achieve energy savings by selecting empirically good paths and by caching and processing data in-network But at the beginning of routing being established, interest must be flooded throughout the network, Directed Diffusion Protocol (DDP) which could meet the features of WSN, such as data-oriented, many-to-one transmissions and low energy costs, together with data aggregation mechanisms which emphasized on cascading timeouts, to eliminate the redundancy caused by the transmission of large amounts of data. This paper presents the description of DD protocol and current developments including the view for which one is best.
