- Exploring the Energy-Latency Trade-Off of Broadcasts in IEEE 802.11 Power Save Networks
- Efficient information dissemination is essential for the operationality of sensor networks. However, one of the challenges to efficient information dissemination arises from only a random subset of nodes being active in any given time. This is mainly due to sensor networks employing power-saving techniques to compensate the energy constraints of...

- Adaptive Two-Tier Energy-Efficient Multicasting in Mobile and Wireless Ad Hoc Networks
- This paper studies the problem of energy-efficient multicasting in mobile and wireless ad hoc networks. To deal with node mobility, the paper presents a two-tier multicasting model which consists of mobile nodes and stationary nodes. Mobile nodes achieve multicasting through the closest stationary node at lower tier. Stationary nodes route...

- A System for Power-Aware Agent-Based Intrusion Detection (SPAID) in Wireless Ad Hoc Networks
- This paper proposes a distributed hierarchical intrusion detection system for ad hoc wireless networks, based on a power level metric for potential ad hoc hosts, which is used to determine the duration for which a particular node can support a network monitoring node. The paper proposes an iterative power-aware power-optimal...

- A Location-Aided Power-Aware Routing Protocol in Mobile Ad Hoc Networks
- In multi-hop wireless ad-hoc networks, designing energy-efficient routing protocols is critical since nodes are power-constrained. However, it is also an inherently hard problem due to two important factors: First, the nodes may be mobile, demanding the energy-efficient routing protocol to be fully distributed and adaptive to the current states of...

- Cross-Layer Analysis for Detecting Wireless Misbehavior
- Intrusion Detections Systems IDSs in ad hoc networks monitor other devices for intentional deviation from protocol, i.e., misbehavior. This process is complicated due to limited radio range and mobility of nodes. Unlike conventional IDSs, it is not possible to monitor nodes for long durations. As a result IDSs suffer from...

- Mobile-Assisted Localization in Wireless Sensor Networks
- The localization problem is to determine an assignment of coordinates to nodes in a wireless ad-hoc or sensor network that is consistent with measured pairwise node distances. Most previously proposed solutions to this problem assume that the nodes can obtain pairwise distances to other nearby nodes using some ranging technology....

- Establishing Trust in Pure Ad-Hoc Networks
- An ad-hoc network of wireless nodes is a temporarily formed network, created, operated and managed by the nodes themselves. It is also often termed an infrastructure-less, self-organized, or spontaneous network. Nodes assist each other by passing data and control packets from one node to another, often beyond the wireless range...

- Forming Optimal Topologies for Bluetooth-Based Wireless Personal Area Networks
- This paper addresses the problem of determining an optimal topology for Bluetooth Wireless Personal Area Networks (BT-WPANs). In BT-WPANs, multiple communication channels are available, through a frequency hopping technique. The way network nodes are grouped to share the same channel, and which nodes are selected to bridge traffic from a...

- Kerberos Assisted Authentication in Mobile Ad-Hoc Networks
- An ad-hoc network comprises mobile nodes that cooperate with each other using wireless connections to route both data and control packets within the network. As the low transmission power of each node limits its communication range, the nodes must assist and trust each other in forwarding packets from one node...

- Path Planning of Mobile Landmarks for Localization in Wireless Sensor Networks
- Many applications of wireless sensor networks require the sensor nodes to obtain their locations. The main idea in most localization methods has been that some nodes with known coordinates (e.g., GPS-equipped nodes) transmit beacons with their coordinates in order to help other nodes to localize themselves. A promising method that...

- Resource Biased Path Selection in Heterogeneous Mobile Networks
- In wireless ad hoc networks heterogeneity is inherent; each node has different characteristics, resources and purpose. Current ad hoc routing protocols do not take node heterogeneity into account when making routing decisions; they consider each node identical in capabilities. This paper proposes a simple way to modify the route discovery...
