Rendezvous design algorithms for wireless sensor networks with a mobile base station
TLDR
This work proposes a rendezvous-based data collection approach in which a subset of nodes serve as the rendezvous points that buffer and aggregate data originated from sources and transfer to the base station when it arrives. Expand
Performance evaluation of scheduling in IEEE 802.16 based wireless mesh networks
TLDR
This work proposes a collision-free centralized scheduling algorithm for IEEE 802.16 based Wireless Mesh Networks to provide high-quality wireless multimedia services and designs a relay strategy for the mesh nodes in a transmission tree, taking special considerations on fairness, channel utilization and transmission delay.

Adaptive location updates for mobile sinks in wireless sensor networks
TLDR
This work proposes a new solution with adaptive location updates for mobile sinks that consumes less energy in each sensor node and also decreases collisions in wireless transmissions, which can be used in large-scale WSNs. Expand
Centralized Scheduling and Channel Assignment in Multi-Channel Single-Transceiver WiMax Mesh Network
TLDR
The simulation results show that the multi-channel single-transceiver MAC can reduce the length of scheduling substantially as compared with the single channel system, and double channel may provide a performance similar to the multiple channels. Expand
Rendezvous Planning in Wireless Sensor Networks with Mobile Elements
TLDR
The design of the rendezvous-based data collection protocol that facilitates reliable data transfers from RPs to MEs in presence of significant unexpected delays in ME movement and network communication is designed. Expand
Rendezvous Planning in Mobility-Assisted Wireless Sensor Networks
TLDR
The design of the rendezvous-based data collection protocol that facilitates reliable data transfers from RPs to MEs in presence of significant unexpected delays in ME movement and network communication is designed. Expand
Aggregation Aware Spectrum Assignment in Cognitive Ad-hoc Networks
TLDR
Aggregation-Aware Spectrum Assignment (AASA), a spectrum assignment algorithm in cognitive ad-hoc networks is proposed and it is proved that AASA optimizes the spectrum assignment and maximizes the number of users that can be supported in the system. Expand
VC-MAC: A Cooperative MAC Protocol in Vehicular Networks
TLDR
This paper proposes a novel protocol called vehicular cooperative media access control (VC-MAC), which utilizes the concept of cooperative communication tailored for vehicular networks, particularly for gateway-downloading scenarios and leverages the broadcast nature of the wireless medium to maximize the system throughput.

Performance Evaluation of Scheduling in IEEE 802.16 Based Wireless Mesh Networks
TLDR
An efficient centralized scheduling algorithm in IEEE 802.16 based wireless mesh networks to provide high qualified wireless multimedia services with special attention on the relay function of the mesh nodes in a transmission tree which is seldom studied in previous research is proposed. Expand
Discriminating DDoS Attacks from Flash Crowds Using Flow Correlation Coefficient
TLDR
A discrimination algorithm using the flow correlation coefficient as a similarity metric among suspicious flows is proposed using the size and organization of current botnets and demonstrated the effectiveness of the proposed method in practice. Expand
