Multiservice delivery is an important research issue in wireless sensor networks (WSNs) integrated with cloud computing, especially for heterogeneous applications which require reliable, timely and fair data delivery in adversarial environments. Therefore, both reliability requirements and delay constraints should be taken into account. Moreover, the delivery protocol should be designed to cater for...
When the use of wireless sensors network is becoming increasingly wider and deeper, its problems are also beginning to highlight. Due to the limit of wireless sensors' energy supply and the unstable channel, ensuring the reliability and speed of the transmission has become the research hot spot. With multipath or retransmission transmission mechanism, the redundancy of data transmission can be ensured...
In this paper, we propose a Fragmentation-based Multipath Routing (FMR) model for Software Defined Networks (SDNs) to enable attack-resilient data transfer. With the use of erasure encoding to fragment a message, the fragments are routed along multiple paths such that no intermediate node receives enough fragments required for message decoding. This ensures that, any intruder on a compromised node...
Traditional routing in the Internet is best-effort. Path differentiation including multipath routing is a promising technique to be used for meeting QoS requirements of media-intensive applications. Since different paths have different characteristics in terms of latency, availability and bandwidth, they offer flexibility in QoS and congestion control. Additionally protection techniques can be used...
Wireless sensor network is used to monitor and record physical conditions of the environment or any other physical object and organizing the collected data at a central location called as base station. Sensor nodes in sensor network are spatially dispersed. In this paper a new protocol REBM (Residual energy based multipath routing protocol) has been created based on residual energies of nodes and...
The usage of wireless sensor networks applications is becoming very important in monitoring and analyzing the environment by utilizing a number of sensor nodes. These sensing nodes are capable of collecting the required data and transmit it to the target application. The wireless sensor nodes use routing protocols for sending data between the nodes of the system as required by the application. These...
Current intra-domain routing protocols computes only shortest paths for any pair of nodes which cannot provide good fast reroute when network failures occur. Multipath routing can be fundamentally more efficient than the currently used single path routing protocols. It can significantly reduce congestion in network by shifting traffic to unused network resources. This improves network utilization...
The Internet is playing an increasingly crucial role in both personal and business activities. Handling link failures is an important task in designing routing protocols. To enhance the network availability without incurring significant extra overhead, we propose a novel link protection algorithm, Hybrid Link Protection Scheme (HLP) to achieve failure resilient routing.
Wireless sensor networks (WSNs) consist of tiny sensor nodes with sensing, computation and wireless communication capabilities. As sensor nodes are resource constrained, the usage of energy and memory must be done wisely to increase the lifetime of nodes. It is also necessary to deliver data reliably to make any application more useful to the end user. In this paper we propose a protocol using cluster...
Disjoint multipath routing is an attractive approach for improving the reliability of data delivery in wireless sensor networks. Recently, the issue for maintaining the robustness and efficiency of the disjoint multipath routing against network failures such as network holes are being studied. Several protocols have been proposed to handle the network failures. However, they cause the large performance...
In the past decade, multipath routing has been proposed to provide reliability for mobile ad hoc networks (MANETs). As wireless mesh networks become more and more popular, performance evaluation of different routing algorithms is required in static scenarios. Performance comparison between unipath routing and multipath routing is conducted in this paper. From the simulation results we find that multiple...
Geographic multipath routing is one of the most appropriate approaches which can improve the end-to-end reliability via multiple paths for the wireless sensor networks that have frequent network dynamics such as both node and link failures. It has been focused on how to construct a node-disjoint multipath that an intermediate node should be belonged by only a single path. It is because that if two...
Energy constraints are undoubtedly a major concern in the creation of algorithms for WSNs. In this paper we examine the issue of extending a wireless sensor network's lifetime, not with the aim of providing a new algorithm, or comparing existing energy-reduction related methods, but with the aim of understanding if this problem can be inherently addressed by other types of algorithms such as those...
A Mobile Ad Hoc Networks (MANETs) is a collection of mobile nodes that can communicate with each other using multihop wireless links without utilizing any fixed based station infrastructure and centralized management. It is very necessary for MANETs to have an efficient routing and quality of service (QoS) mechanism to support diverse applications. Multipath routing allows the establishment of multiple...
Although the IEEE 802.16 standard defines various QoS classes and their associated parameters, it does not define the scheduling, routing, and Call Admission Control (CAC) algorithms to be used in the network. It is left unstandardized for vendor differentiation. Currently, scalable distributed scheduling and routing algorithms are available for IEEE 802.16 mesh networks. But, the existing CAC algorithms...
Mobile Ad-hoc NETwork (MANET) is a collection of wireless mobile nodes without any fixed base-station infrastructure and centralized management. Topological changes in MANETs render routing paths unusable. The multipath routing addresses this problem by providing more than one route to a destination node. Shared links and nodes between paths present common failure points which can disable many or...
In this paper, we exploit the geographic opportunistic routing (GOR) for QoS provisioning with both end-to-end reliability and delay constraints in wireless sensor networks (WSNs). Recent work exploits multipath routing to guarantee both reliability and delay QoS constraints in WSNs. However, the multipath routing approach suffers from a significant energy cost. We also find that existing GOR protocol...
While transparent optical networks become more and more popular as the basis of the next generation Internet (NGI) infrastructure, such networks raise many security issues, which do not exist in traditional optoelectronic networks. The existing protection schemes which rely heavily on fault detection with the use of network monitoring performed by optoelectronic conversion at the switching nodes,...
This paper present a novel packet delivery mechanism only using local information for probabilistic non-dominated guarantee of high data confidentiality and reliability in wireless sensor networks. In the data confidentiality domain, a secret message is transformed into multiple shares by secret sharing schemes and then forwarding towards destination via multiple neighbours so that even if a small...
This paper presents FDF (false destination forwarding), a technique that can be adopted for multipath routing in wireless sensor networks to avoid the overhead caused by the maintenance of disjointed or partially disjointed routing paths. FDF changes the packet destination target as the packet itself proceeds along the path: this way, it does not require any change to the underlying geographic routing...
