چکیده
In this paper we present the applications of image encryption techniques and channel coding techniques, to design scheme effective for secure image transmission over wireless channels, we present three proposed scheme as follow: First scheme apply image encryption by a combination of hybrid chaotic maps using Baker map and our proposed Hénon chaotic map 3 in three different modes of operations, beside using fractional Fourier transform (FRFT). Second image encryption scheme is combine the main advantages of FRFT, Arnold cat map for confusion and our proposed Hénon chaotic map 3 for diffusion. Third scheme based on combination of hybrid chaotic encryption and low density parity check (LDPC) to secure transmission of image over wireless channel. Our proposed scheme improve throughput. The proposed scheme enhanced the performance parameters and achieved both security and reliability of image transmission over wireless channels.

Combination of Hybrid Chaotic Encryption and LDPC for Secure Transmission of Images over Wireless Networks
Robust and secure transmission strategy for high quality image through wireless networks is considered a great challenge. However, the majority of encrypted image transmission schemes don't consider well the effect of bit errors occurring during transmission. These errors are due to the factors that affect the information such as noise and multipath propagation. That should be handled by an eff...

متن کاملA New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...
متن کاملSecure Communication in Shotgun Cellular Systems
In this paper, we analyze the secure connectivity in Shotgun cellular systems (SCS: Wireless communication systems with randomly placed base stations) by Poisson intrinsically secure communication graph (IS-graph), i.e., a random graph which describes the connections that are secure over a network. For a base-station in SCS, a degree of secure connections is determined over two channel models: ...
متن کاملOptimization of Energy Consumption in Image Transmission in Wireless Sensor Networks (WSNs) using a Hybrid Method
In wireless sensor networks (WSNs), sensor nodes have limited resources with regard to computation, storage, communication bandwidth, and the most important of all, energy supply. In addition, in many applications of sensor networks, we need to send images to a sink node. Therefore, we have to use methods for sending images in which the number and volume of packets are optim...
