Cryptography helps solve many computer and communication problems, including clock synchronization, where a group of nodes wants to agree on a theoretically unique clock in the system with the presence of malicious nodes trying to prevent the process of convergence; so we will need a set of mechanisms, including encryption. Many synchronization techniques suffer from high power consumption or vulnerability to attack or difficulty of implementation. In this article, we propose a synchronization protocol that contains two parts. The first part uses a lightweight linear scheme to encrypt clock messages to fend off certain types of attacks such as message manipulation. This scheme is suitable for Wireless sensor networks (WSNs) with negligible encryption and decryption time. The second part is the process of calculating the clock based on a very simple consensus algorithm. The study of the proposed protocol has shown very satisfactory results.

“…However, it is obvious that a geographical area could contain several radio networks on the same frequency band. In this case, internetwork 1 time synchronous operation would be beneficial, e.g., if dynamic spectrum access or frequency hopping are applied, since that would minimize interference between networks and optimize the use of frequency resources. In addition to communications reasons, several applications would benefit from a common time.…”

“…Consequently, network time synchronization (NTS) is of great interest both in individual networks but also over different networks though the latter subject is not usually touched in the ad hoc network context. As an additional viewpoint, one of the networks could contain a high quality time source that other networks should or even are required 1 "Two or more networks connected by routers and bridges.

Several time synchronous ad hoc networks may operate in a same geographical area. Although network time synchronization within an individual network has been discussed a lot, internetwork time synchronization relying on time sources the networks carry has not been addressed. Therefore, this paper proposes an internetwork time synchronization procedure that allows to use one network as a time source and share its time, like a global navigation satellite system time, to other networks. In addition, the paper proposes a generic hybrid network time synchronization protocol and analyses its performance using a sensible metric called a mutual consensus. It is shown that the common time is achieved with a limited variance in the networks that operate in the master-slave, distributed or hybrid mode. Provided numerical examples illustrate the behavior of the algorithm and confirm the theoretical findings.

The packet transmission among sensor nodes mainly focuses on clock synchronization. This paper proposes a protocol for efficient clock synchronization in energy based approaches to overcome the clock synchronization invariances and communication overheads. Clustering technique helps to design the sensor network architectures and broadcast the sensor nodes. The existing Mobility Zonal Based Stable Election Protocol (Mob-ZSEP) protocol identifies best path using clustering approach. The selected best path using Mob-ZSEP routing protocol will be utilized by proposed clock synchronization protocols. This research paper proposes two novel protocols: Energy based Proportional Integral and Least Common Multiple (EPILCM) and Weighted based Least Common Multiple (WLCM). EPILCM protocol hybrids two methods such as Energy based Proportional Integral (EPI) and Energy based Least Common Multiple (ELCM). The proposed EPILCM protocol is used for clock synchronization using energy based approach which reduces energy consumption, synchronization error, propagation delay, clock inaccuracy and communication overhead. WLCM protocol performs transmission based on the weight of the packet in sensor networks. The EPILCM, WLCM protocols are compared and the simulation results shows that EPILCM protocol outperforms WLCM protocol.
