Sensor networks deployed in hostile areas are subject to node replication attacks, in which an adversary compromises a few sensors, extracts the security keys, and clones them in a large number of replicas, which are introduced into the network to perform insider attacks. Memory overhead, energy efficiency and detection probability are the main technical concerns for any replication detection protocol...
Wireless sensor networks (WSNs) have received more and more attention on the object tracking system, but the performance of active routing is low. In this paper,we present an novel energy efficient dynamic target tracking (EE-DTT) protocol for wireless sensor network, EE-DTT has three obvious features: firstly, it improves virtual grid ideas to divide each cluster into MtimesN square area and select...
One of the key problems for wireless sensor networks (WSNs) is how to make the best of limited energy. The conventional clustering method has the unique potential to be the framework for energy-conserving wireless sensor networks .In this paper, a novel dynamic clustering algorithm based on geographical location information(GL-DC)is proposed for WSNs. Comparing with other algorithms, GL-DC has two...
A wireless mesh network (WMN) provides a flexible and low-cost solution for end users to connect to the Internet through its multi-hop infrastructure. For such a network to proliferate, a fundamental problem that must be solved is to ensure the fair allocation of network bandwidth to all participating parties. This paper proposes a cross-layer design for achieving end-to-end maxmin fairness in WMNs...
Wireless sensor networks (WSNs) have received more and more attention due to the limited energy of battery-powered nodes, but rarely consider the maximum lifetime and the shortest path at the same time. In this paper, we present an energy-efficient algorithm for maximum lifetime and minimum routing (EE-MLMR) in wireless sensor networks. EE-MLMR improves energy utility by changing the activity of wireless...
One of the key problems for wireless sensor networks (WSNs) is the design of energy-efficient routing algorithm, because sensor energy is limited. The energy-efficiency routing algorithm has a strong impact on the network performance. In this paper, we present an energy-efficient minimum routing algorithm (EEMR) of wireless sensor networks. EEMR improves energy utility by changing the activity of...
One of the most critical issues in wireless sensor networks is represented by the limited availability of energy on network nodes; thus, making good use of energy is necessary to increase network lifetime. In this paper, we present an energy-efficient maximum lifetime (EEML) algorithm in wireless sensor networks. EEML improves energy utility by changing the activity of wireless communication module...
