Energy efficient routing is the paramount point of significance in any wireless sensor network (WSN) so that the network sustains without any human intervention. Various energy efficient protocols have been proposed, multi-level Low Energy Adaptive Clustering Hierarchy (LEACH) being one among these. The multi-level LEACH protocol involves election of cluster heads at various hierarchical levels. If the area of deployment is large, the farther cluster heads cannot reach the base station directly. In such cases, it is needed to make use of an energy efficient routing technique for communication among cluster heads and forward the data towards the base station. Energy consumption is reduced by adopting routing mechanisms based on multi-hop and inverted tree in this multi-level LEACH protocol. This work deals with multi-level LEACH comprising of 1L-LEACH and 2L-LEACH. Directed diffusion carried out in 1L-LEACH and flat topology are compared with flooding. In directed diffusion, routing is done between a source and a sink optimizing the path taken. NS-3 simulation platform has been used and the results are presented.

“…The two-phase pull model of directed diffusion may be easily extended to support real-time data flows. The primary additions to diffusion required for RTDD [5] are a prioritized queue and a scheduling policy. We have developed both static and dynamic scheduling policies for RTDD equivalent to SVM and DVM in RAP.…”

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.

Heterogeneous network convergence and emergency data transmission has become very hot in recently years. This paper proposed an adaptive transmission scheme to achieve Quality of Service (QoS) guarantee transmission when the emergency is found in multi-service sensor network. This scheme reduces the emergency data transmission delay and guarantees reliable emergency data transmission with the assistance of cellular networks. The source node which detects the emergency connects with the user equipment (UE) with Wireless Sensor Network (WSN) and cellular network interface, and then transmits data to the command center with cellular network. Numerical simulation shows that low delay and low packet loss ratio can be achieved for emergency traffic compared with the conventional scheme in WSN.
