Mobile ad hoc network (MANET) is infrastructure less system of communication. Many remote areas where infrastructure based systems are not feasible. MANETs provide the perfect solution for that situation. Although, MANETs use various routing protocols but Dynamic Source Routing (DSR) is the widely used routing protocol among them because of the flexibility and efficiency of the protocol. MANET usually takes battery power for the operation and it determines the lifetime of MANET. In this paper, we have proposed two modifications in the algorithm of traditional DSR to increase the lifetime of MANET. It will prevent the network from being partitioning and helps node from being sinking down. Initial energy of node will determine the behaviour of the MANET. We have simulated our proposed methodology in ns2.35 and results are found impressive. It works perfectly at lower initial energy of nodes.

In this paper, Taylor series expansion is used to design the variable IIR fractional delay filter. The proposed design is based upon collective response of two IIR filters having first-order. The Al-alaoui operator with α-approximation differentiator and reasonable modifications in this differentiator are caused to be designing these filters. The constructed Farrow structure is more computationally efficient than existing structures. In the end, to illustrate the effectiveness of proposed design approach magnitude response and group delay response are shown.Keywords

Objectives: To improve the factors such as BER (Bit Error Rate), Channel Capacity, Gain and SNR (Signal to Noise Ratio) using the enhanced technique. Methods/Statistical Analysis: We proposed a new efficient technique called Multiple Access Differential Noise Shift Keying (DNSK) along with convolution detector based on the modulation and demodulation. Findings:The proposed modulation configurations are specified, analytical terminologies intended for Bit Error Rate are derived and it verified by computer simulations over Rayleigh, Gaussian and Additive White Gaussian Noise (AWGN). The simulation result shows that the proposed method overtakes classical noise shift communication schemes regarding bit error rate (BER) in the multiuser state. Application/Improvements:In existing method the improvisation of Bit Error Rate and gain has done by Chaos shift Keying and it achieves the Bit Error Rate and gain at the rate of -0.003 and 0.5 dB respectively. In our research the modulation and demodulation has done by Differential Noise Shift Keying and achieves the Bit Error Rate and Gain at the rate of 0.1 and 1.12 respectively.Keywords
