Abstract
To secure the multimedia informations, cryptography is an active methods for information sSecurity has been utilized in some practical stechniques. Most of these stechniques have become swidely challenging, due to a numbers of weaknesses such as,the limitations of storages in memory, bandwidth, and the unreliability of the timing requirements. Besides, these data usually needss to encryption and compression for efficient ssecurity, storages and transmissions. Ones of the major sweaknesses for wireless sensor network is the energy sconsumption, because of the batterys replacements or the difficult recharging. The energy consomption can be controlled by more than ones layer in WSNs. This paper, focused on the image security with major enhancement on the energy consumption sover physical layer, because most of the energy consumption soccur in this layer. The reduction will be accomplished by using the Zigbee transceivers standard at the physical layer with the minimum complexity and lower power consumption sthan other systems used in wireless sensor networks. Additionally, such use will also improve energy efficiency and bits error rate of the wireless sensor networks. Also the chaos systems was applied to the pixels, bits and chips. The enhancement simulation for bit error rate and peak signal to noise ratio by transceiver image cameraman through an AWGN and Rayleigh fading channels are displayed. The enhanced transmitting image by 5 dB signal to noise ratio on the Rayleigh fading channel, an improvement on the peak signal to noise ratio of the received image from 23.5 dB to 37 dB can be observed.
