WBAN is the limited version of the WSN. The area covered by network is the main constrained in the WBAN as compared to the WSN. Various routing protocols applicable in the WSN must have optimized performance in WBAN. This paper analyzes the performance of the various routing protocols of the wireless network in the WBAN and WSN. Moreover, the paper also compares their performance in the same network...
Wireless Sensor Network (WSN) is a collection of sensor nodes capable for sensing instantaneously. WSNs are widely deployed in hostile environment on ad-hoc basis. Routing protocols are used to discover a suitable route among sensor nodes and transfer sensed data from one node to another node. Several routing protocols are developed and configured according to their characteristics. Ad-hoc nature...
With the increasing popularity of mobile devices, recent developments in wireless communication and the deployment of wireless sensor networks in the hostile environment makes it the popular field of interest from research perspective. Sensor networks consist of ‘smart nodes’ communicating wirelessly which are resources constrained in terms of memory, energy, computation power. The design of these...
Wireless sensor networks are spatially distributed network of autonomous nodes that are used in the monitoring of physical and environmental conditions. Since these sensors have limited energy to work with, their storage and processing capabilities are very much basic. They also have very limited transmission range. Recent approaches have seen immense investments using WSN that demands sensor networks...
Wired network nodes have direct connection with the power source. But wireless sensor nodes depend on the on-board battery for power. Two different things can be done to increase the operational lifetime of the WSN. First one is efficient energy utilization. Second one is attachment of power generating devices. This paper proceeds with efficient energy utilization by proposing a new multipath routing...

Through theoretical analysis and simulation experiments to verify the performance of the protocol, and compared with the LEACH protocol. The results show...
Opportunistic routing is considered a promising direction for improving the performance of wireless sensor networks (WSN). In opportunistic routing, the intermediate nodes collaborate on packet forwarding in order to achieve high throughput in the face of lossy links. That makes the next node selection process crucial. In this paper, we are presenting an opportunistic routing protocol for wireless...

In the paper, it is introduced of the system's composition structure and Working principle,...
Ad hoc networks are threatened by a wide variety of accidental and malicious faults. This fact limits the practical exploitation of ad hoc networks. In consequence, apart from enforcing the dependability and security aspects of these networks, the provision of approaches to evaluate their behaviour in the presence of faults and attacks is of paramount importance. Accordingly, analysing and determining...
The growing popularity of wireless sensor networks (WSNs) lead to the shifting of research focus from WSNs to wireless multimedia sensor networks (WMSNs). Most existing routing protocols for WSNs do not satisfy the need of continuous and higher data rate routing requirements of WMSNs. In this paper a new routing protocol (LEAR) for WMSNs has been proposed which establish routing paths based on node...
Rumor routing is a routing protocol based on query for wireless sensor networks, which selects next hop randomly during establishing path and the path may not be optimal and may be loop. So this paper puts forward a novel rumor routing (NRR), which bases on ant colony optimization and can resolve the loop route that established by rumor routing, and has good convergence, comparing to rumor routing,...
Location-based multicast routing (LMR) technique can increase the lifetime and the channel capacity of wireless sensor network (WSN) by reducing the number of duplicated data transmissions and control messages. Previous LMR algorithms can suffer performance deterioration in real deployments because they consider only location of nodes and can transmit packets across concrete walls or other interfering...

Reliable data transfer (RDT) is one of the key issues in wireless sensor networks (WSNs) and can be achieved by using link-level re-transmissions and multi-path routing. Another key issue is the scalability of WSNs.

Clustering algorithm utilizes multi-hop communication which generates “hot zone” issues in wireless sensor networks. This paper presents a new energy-balanced adaptive hierarchy routing protocol which is called EAHRP. It establishes different intervals of hierarchical structure according to the distance between nodes and the sink. It adopts the methods of cluster-head selection based on region and...
For traditional anonymous routing protocols for wireless sensor networks (WSNs), the routing path is a single path, and the invalidation of any one routing node in the routing path will result in the failure of the whole routing path, this is extremely difficult in practice to guarantee the reliability of message delivery. In this paper, a secure anonymous routing protocol for wireless sensor network...
