In this paper, we propose a media-specific forward error correction (FEC) method based on Huffman coding for distributed speech recognition (DSR). In order to mitigate the performance degradation of DSR in noisy channel environments, the importance of each subvector for the DSR system is first explored. As a result, the first subvector information for the mel-frequency cepstral coefficients (MF...
Vehicular Ad-Hoc Networks (VANETs) have recently gained considerable attention from both research and industry communities. One of the challenges posed by the study of VANETs is the definition of routing protocols design. In this paper, a realistic simulation environment is developed based on Mobility model generator for Vehicular networks (MOVE) and Network Simulator (NS2). The performance of ...
Because of several constraints in ad hoc networks, an adaptive ad hoc routing protocol is increasingly required. In this paper, we propose a synopsis of an adaptation process for an adaptive ad hoc routing protocol. Next, we put into practice the analysis of the process of adaptation to mobility by realizing an adaptive routing protocol: CSR (Cluster Source Routing) which is an extension of a w...
A Mobile Ad-hoc network (MANET) consists of a number of mobile wireless nodes, among which the communication is carried out without having any centralized control. MANET is a self organized, self configurable network having no infrastructure, and in which the mobile nodes move arbitrarily. The mobile nodes can receive and relay packets as a router. Routing is a critical issue and an efficient r...
This paper evaluates the performance of two prominent on-demand routing protocols, which are Dynamic Source Routing (DSR) and Ad Hoc On-Demand Distance Vector Routing (AODV) for wireless sensor networks. Results obtained from simulations demonstrates that even though DSR and AODV share a similar on-demand behavior, the differences in the protocol mechanics can lead to significant performance di...
Streaming multimedia applications over Mobile Ad Hoc Networks (MANETs) create new challenges to routing protocols in terms of stringent performance requirements. Many routing protocols that have been proposed in the past could not completely address these issues. In the present paper, the original DSR protocol is modified to provide multi-path data transfer during the periods of congestion. NS-...
Strategies to augment anti-cancer immune responses have recently demonstrated therapeutic utility. To date clinical success has been achieved through targeting co-inhibitory checkpoints such as CTLA-4, PD-1, and PD-L1. However, approaches that target co-activatory pathways are also being actively being developed. Here we report that the novel TLR7-selective agonist DSR-29133 is well tolerated i...
This paper presents a framework for node distribution with respect to density, network connectivity and communication time. Using NS2, we evaluate and compare performance of three routing protocols; Ad-hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Fisheye State Routing (FSR) both in MANETs (IEEE 802.11) and VANETs (IEEE 802.11p). We further enhanced these protocols by c...
Dissipative soliton resonance (DSR) is a phenomenon where the energy of a soliton in a dissipative system increases without limit at certain values of the system parameters. We have found that the DSR phenomenon is robust and does not disappear when perturbations are introduced into the model. In particular, parameter management is benign to DSR: the resonance property remains intact even when ...
