In this paper the applicability of a fault tolerance synchronization algorithm is presented through data packet headers. Packet headers provide indicts for networking equipment on what must be done and in the case of real-time persistent routed sessions, these are a concise guideline on how to tune each parameter. Real-time sessions are transmitted with connection oriented protocols and need a constant...
DTN (Delay/Disruption Tolerant Networking) inserts a new layer between the application layer (L7) and the transport layer (L4) for reliable communication on long-delay, intermittent, or lossy inks. Such a new layer, however, should provide not only a single rich service but also various rich services. We are proposing Layer-5 (L5) inserted between L7 and L4 to provide multiple rich services. One of...
Providing better energy efficient network is the important critical issues in Wireless Sensor Networks (WSNs). We present Multi-constraint Energy Balanced Opportunistic Routing (MEBOR) algorithm that enhance the network lifetime. Proposed algorithm is devised with unique parameters viz., Single hop Packet Progress (SPP), Packet Reception Ratio (PRR), Residual Energy and Energy Density to select intermediate...
End-to-end communication usually adopts a single path to transmit interactive packets in traditional routing mechanisms, so attackers can easily snoop into the whole communication trace to analyze users' typical features and to predict users' next-behaviors, which can severely decrease the security of users' information. Thus, this paper puts forward a multi-path based link-state routing mechanism,...
We present the framework for a heterogeneous internetworking service architecture to provide probabilistic quality of service guarantees to short critical messages prior to transmission. The TCP/IP Internet is not suited to bear mission-critical data across administrative domain boundaries with stringent delivery requirements because Border Gateway Protocol obscures network state information. Critical...
The message propagation with low delay becomes a fundamental challenge in VANET. The vehicle Ad hoc networks are a very appealing solution for many safety applications like assistance driver, warning about collision of vehicle, warning of distance between vehicles, cooperation during driving and control for cruise cooperation. To operate these application the vehicles are fitted with those equipments...
Wireless sensor network mainly focuses on monitoring particular area for event and sending detected event to the destination as soon as possible and in reliable manner. In WSN some methods uses single node to send event packet, some methods uses multiple nodes and some method uses all nodes in particular region where event is detected to send event packet to the destination. In this paper we focus...
This study outlines the challenges in developing a platform to support environmental monitoring, and demonstrates a solution approach based on the modification of a popular reactive routing protocol known as Ad-hoc On-demand Multipath Distance Vector (AOMDV). The proposed modifications (event based, robust routing functions) in AOMDV are desirable to facilitate better wireless connectivity for current...
Due to the instability of underwater environment, the reliable data transfers is more sensitive issue in Underwater Wireless Sensor Networks (UWSNs) as compare to land based sensor network. Underwater networks are mostly designed by acoustic sensor nodes and surface sinks that are connected to any onshore control center. Acoustic channel characteristics are create many problems like, low bandwidth;...
Reliability in IP-multicast forwarding becomes useful while operating in lossy environment of wireless sensor networks. RPL is a protocol for forming a multicast tree in sensor networks for multicast data forwarding. Trickle multicast uses RPL to provide reliability, however it has a high overhead and delay, especially when a radio duty cycle is used on the sensors. Stateless Multicast Forwarding...
WSNs hold the promise of many new applications that require the network to handle traffic with different priority levels and QoS requirement in an energy efficient way while avoiding collisions and interference. In this paper, we investigate several aspects related to the application requirements and the network states and resources in order to provide multi-QoS routing protocol for WSNs. We propose...
Challenges of the existing power grid demand the integration of information and communication technologies into the next-generation electric grid, namely the Smart Grid (SG). This paper focuses on the critical communications segment corresponding to the consumer-premise, the Neighbor Area Network (NAN). For this segment, Greedy Perimeter Stateless Routing (GPSR) protocol is considered for its low...
To improve safety, a warning message in VANETs should be delivered both reliably and urgently. Existing solutions either tend to compromise propagation delay or do not reach high reliability due to broadcast storm problem caused by excessive retransmissions. We propose Receiver Consensus, which exploits geographical information to help nodes autonomously achieve agreement on forwarding strategies...
Wireless sensor networks (WSNs) are becoming a viable tool for many monitoring applications. In many cases these applications may be of critical nature where the transmitting of vital information from sensors to base station or sink is crucial, and data loss cannot be tolerated. As a result, the information transmission of wireless sensor networks has various different requirements in performance,...
