Wlan-to-wwan handover methods and apparatus using a wlan support node having a wwan interface
TL;DR: In this paper, a network support node which is utilized to facilitate such transitioning has a first communication interface (e.g. an Ethernet interface) for connection with a communication network which includes the WLAN and a second communication interface for communicating with a base station of the WWAN over a wireless communication link.

Overload control in SIP networks using no explicit feedback: A window based approach
TL;DR: This paper proposes a distributed and end-to-end adaptive window based overload control algorithm, which does not use explicit feedback from the downstream server, and achieves higher throughput and is also fair among different upstream servers under different network latencies.
Journal ArticleDOI
Energy-aware and load-balanced parent selection in RPL routing for wireless sensor networks
TL;DR: This paper proposes a dynamic parent selection in RPL that takes both load and energy constraints into consideration and extends network lifetime and improves network performance in terms of end-to-end delay and packet delivery ratio.
Proceedings ArticleDOI
QoS based aggregation in high speed IEEE802.11 wireless networks
TL;DR: A novel frame aggregation algorithm with statistical delay guarantee for high speed IEEE802.11 networks considering link quality fluctuations and outperforms Earliest Deadline First (EDF) scheduling with maximum aggregation size and pure deadline-based aggregation, both in terms of maximum number of stations and channel efficiency.
