Today TCP/IP congestion control implements the additive increase/multiplicative decrease (AIMD) paradigm to probe network capacity and obtain a “rough” but robust measurement of the best effort available bandwidth. To improve the efficiency of congestion control, Westwood TCP proposes an additive increase/adaptive decrease paradigm that adaptively sets the transmission rate at the end of the pr...

In this writeup, we summarize the extensions made to TCP (relative to what I teach in the Internet architecture/protocols course). The list includes: 1. Larger window sizes accommodated through a window scale option is proposed for LFNs (Networks with Long Fat Pipes) [1], which are networks that have large values of the delay bandwidth product (DBP). TCP performance depends upon this product. T...

Poverty and attempts to alleviate it is an issue that has continued to generate interest of national governments and international agencies and mostly in most developing countries. The Christian Church, in spite of its central mandate being spiritual evangelism has continued to participate in the fight against poverty to accomplish Jesus Christ's mission to whole-heartedly serve and minister to...

Internet of Œings (IoT) is characterized by various of heterogeneous devices and facing numerous threats. Modeling security of IoT is still a certain challenge. Œis paper de€nes a Stochastic Colored Petri Net (SCPN) for IoT-based smart environment and then proposes a Markov Game model for security situational awareness (SSA) in the de€ned SCPN. All possible aŠack paths are computed by the SCPN,...

Battery energy limitation has become a performance bottleneck for mobile ad hoc networks. IEEE 802.11 has been adopted as the current standard MAC protocol for ad hoc networks. However, it was developed without considering energy efficiency. To solve this problem, many modifications on IEEE 802.11 to incorporate power control have been proposed in the literature. The main idea of these power co...

We propose a reliable multicast MAC protocol based on the multicarrier direct-sequence code-division multiple access (MC DS-CDMA) scheme to enhance spatial reuse efficiency in wireless local area networks (WLANs). Conventional multicast MAC protocols using RTS-CTS handshake exchange CTS and ACK packets consecutively for reliable transmission. Although this protocol guarantees transmission relia...
