Network lifetime is a key design metric in MANETs, it is considered as one of the most important parameters algorithms to be used in ad hoc networks. Each network node works completely independently and acts as a router for relaying communications. If some nodes die prematurely because of battery depletion, the network lifetime will be adversely affected, and the network will get disconnected. This article presents AOMDV-LP, a new AOMDV lifetime-prolonging routing algorithm for MANETs. This new algorithm helps to maximize the network lifetime by managing nodes energy, link cost and controlling the networks congestion. Simulations quantify the performance gains of the authors algorithm.

Statistical tests have been used to adjust the Zemmouri seismic data using a distribution function. The Pareto law has been used and the probabilities of various expected earthquakes were computed. A mathematical expression giving the quantiles was established. The extreme values limiting law confirmed the accuracy of the adjustment method. Using the moment magnitude scale, a probabilistic model was made to predict the occurrences of strong earthquakes. The seismic structure has been characterized by the slope of the recurrence plot Ȗ, fractal dimension D, concentration parameter K sr , Hurst exponents H r and H t. The values of D, Ȗ, K sr , H r , and H t diminished many months before the principal seismic shock (M = 6.9) of the studied seismoactive zone has occurred. Three stages of the deformation of the geophysical medium are manifested in the variation of the coefficient G of the clustering of minor seismic events.
