Dynamic Source Routing (DSR) Protocol is a commonly applied reactive protocol for mobile ad hoc networks (MANETs). When the network size is increased, overhead is increased due to the source routing nature of DSR. Moreover, energy consumption of the nodes increases, as the nodes act as intermediate nodes for many source destination pairs. In order to(More)
Trellis Coded Modulation with 32-Dimensional Constant Envelope Q2PSK is presented in this paper. TCM combines coding with modulation in such a way that the Euclidean distance is maximized and conserves bandwidth by doubling the number of constellation points of the signal. This way bit rate increases but the symbol rate remains the same. Q<sup>2</sup>PSK is(More)
Mobile Ad Hoc Networks (MANETs) are multi-hop wireless networks where all nodes cooperatively maintain network connectivity. When the size of the network is large and the nodes are highly mobile, the frequency of link failure and energy consumption of the nodes will be more. Link failure will be identified only during the transmission of data packets. Due(More)
The reactive dynamic source routing (DSR) protocol is a commonly applied protocol in mobile ad hoc networks ( MANETs). When the network size is increased, it is observed that the overhead is also getting increased due to the source routing nature of DSR and this in turn reduces the efficiency of DSR protocol. In order to improve the scalability of DSR,in(More)
Mobile Ad hoc Networks (MANETs) operates on basic underlying assumption where all participating nodes are fully collaborated in self-organizing functions. However, performing network functions consumes energy and other resources. Therefore, some network nodes may decide against cooperating with others. The selfish nodes, also termed as misbehaving nodes,(More)
The data loss or corruption of data during the transmission in Wireless Body Area Networks (WBAN) is relatively high. To provide fault-tolerance and to avoid data loss in WBAN during transmission, Adaptive Reliable Cooperative Data Transmission technique (ARCDT) is proposed. By this technique, the data transmission loss is avoided by using a multi-relay(More)
To meet the demand for high speed transmission of image in efficient image storage and remote treatment, the efficient image compression is essential. The contourlet transform along with wavelet theory has great potential in medical image compression. The proposed technique aims at reducing the transmission cost while preserving the diagnostic integrity. In(More)
Collective behavior refers to how individuals behave when they are exposed in a social network environment. This collective behavior gives the opportunity to predict online behaviors of users in a network, given the behavior information of some actors in the network. But Many social media (Facebook, Twitter, YouTube etc..) tasks can be connected to the(More)
Mobile ad hoc networks (MANETs) are multi-hop wireless networks where all nodes cooperatively maintain network connectivity. When the nodes are highly mobile and the size of the network is large the frequency of link failure is increasing. Link failure is identified only during the transmission of data packets. Due to this, latency and control load of the(More)
