Lifetime Optimization via Network Sectoring in Cooperative Wireless Sensor Networks

Wireless Sensor Network 2010年第12期2卷 905-909页

作者： hadi jamali Rad Bahman Abolhassani Mohammad Abdizadeh 不详

Employing cooperative communication in multihop wireless sensor networks provides the network with significant energy efficiency. However, the lifetime of such a network is directly dependant upon the lifetime of each of its individual sections (or clusters). Ignoring the fact that those sections close to sink have to forward more data (their own data plus the data received from the previous sections) and hence die sooner with considering equal section sizes, leads to a sub-optimal lifetime. In this paper, we optimize the section sizes of a multihop cooperative WSN so that it maximizes the network lifetime. Simulation results demonstrate a significant lifetime enhancement for the proposed optimal sectoring.

Objective:To compare the the effects of the diets containing various fish viscera meal and effects of probiotic bacteria(Lactobacillus sp.,Bifidobacterium *** Streptococcus sp.)on the growth,survival and carcass composition of rainbow trout ***:Twelve tanks consisting of triplicates for each treatment group were *** groups of rainbow trout(176 mg bodyweight)were fed with three diets formulated with viscera meal(VM)derived from common carp(Cyprinus carpio),or VM derived from mullet(Liza saliens and Liza auratus)or commercial diet with in-tank probiotic respectively,and three diets without probiotic 4 times a day at 5%to 6%of body weight for 45 *** trout larvae(average individual weight,176 mg)were randomly distributed with density of 4 fish/L into 18 fiberglass *** probiotic treatments a blend of selected bacteria at 104 CFU/mL were added into rearing tanks four times a *** the end of the 45-day experiment,growth performance,survival rates and carcass composition of larvae were ***:The results indicated that change to probiotic diets significantly affect growth and survival of rainbow trout larvae(P<0.05).Rainbow trout larvae fed with commercial diet with in-tank probiotics showed the highest survival rates(98%),total weight(2226 mg)and specific growth rates(7.16%/d)among treatment ***:VM derived from common carp can successfully replace more than half of marine fish meal in formulated diets for rainbow *** of in-tank blends of Lactobacillus sp.,Bifidobacterium *** Streptococcus sp.,can increase survival rates and specific growth rates in rainbow trout larvae.

Some aspects of the life history of Cobitis avicennae(Actinopterygii:Cypriniformes:Cobitidae)from Western Iran

Objective:To describe the age structure,growth,reproductive characteristics and lengthweight relationship of Cobitis avicennae(***)population inhabiting the Gamasiab River,Western ***:*** was collected throughout the spawning season(February to July,2015)in Gamasiab River and its age,growth,and reproductive traits were *** length was measured to the nearest 1 mm,and total weight and gonad weight to the nearest 0.001 *** age was determined using *** was determined by examination of the gonad *** number of eggs was estimated by gravimetric *** egg diameter was examined by measuring 30 eggs for each female with an ocular micrometer ***:The maximum age was 3 *** specimens size ranged from 32.63 to 100.00 mm in total length,weighing from 0.22 to 5.17 g in total ***-weight relationship was estimated as W=1E-05TL^(2.85)for females,W=1E-05TL^(2.83)for males and W=7E-06TL^(2.94)for the *** growth model was isometric for males and sexes combined and negatively allometric for *** absolute fecundity ranged between 132 and 900 eggs with a mean of 490.55 ***:The life history traits described for *** from the Western Iran basin indicated a moderate life span,a moderate body weight,a short duration of spawning season,relatively high heterogeneity in egg size and low egg *** life history traits of *** demonstrated obvious differences compared with its closely related species,indicating that latitude and local environment conditions are important selective forces for this species.
